When you buy a new CMS, the sticker price is only a fraction of the cost you must account for when migrating. Additional time and resources need to be accounted for, even more so if your initial migration doesn’t go right.
Assembling a cross-functional migration team and defining a clear migration strategy is essential to a successful migration.
Your current CMS (if you have one) plays a key role in how easy the migration process is, with those companies migrating from a legacy or monolithic CMS having it harder than those moving from a headless CMS.
Content and data management is arguably the most difficult aspect, as careful content audits and modeling are required. Yet other factors, such as roles and permissions, onboarding, and testing, must be considered.
Content is the key ingredient for most successful brands in the modern age. With the number of options available to customers, the assortment of digital channels, and always-on entertainment, businesses that can successfully use content to capture and keep their customers’ attention will continue to thrive today.
In order to facilitate these content experiences, many organizations are well aware of the need for a robust content management system. They spend weeks assessing various vendors and whether or not they’re capable of meeting their ever-expanding list of requirements until, after a drawn-out search, they find the answer they’ve been looking for.
However, selecting a new web content management system is the first step; executing a seamless CMS migration is the real challenge. Easier said than done, of course, as there are several factors to consider when performing a CMS migration, many of which you might not have deemed necessary at the time or weren’t aware of.
A standard CMS implementation can cost anywhere from thousands to hundreds of thousands of dollars depending on the organization’s size, the number of people or teams needing to use the platform, and sometimes the number of content assets you own.
And the reality is the sticker price that comes with your new CMS might only be a fraction of what you genuinely need to spend in terms of time and other resources. Therefore you need to dig deeper to uncover the actual cost of a CMS migration.
Whether you’re leaving a monolithic legacy platform or moving from one headless CMS to another, this guide will help you to map out and stick to your migration journey every step of the way.
CMS migration is a complex process that can have significant implications for your business. The benefits of moving to a new platform are evident, such as increased flexibility, better features, and support, and often warrant the cost. However, before ascertaining the true cost of your current and future content platforms, there’s another cost to consider — the cost of getting the migration wrong.
A poorly planned migration will cost you time and money at various stages. Switching any software solution can be expensive, and any mistakes made during the process can add up quickly. For instance, if you fail to fully evaluate your new CMS capabilities and opt for one that doesn’t meet your requirements, you may have to pay for additional plugins or development work, which can significantly increase your expenses.
Another financial cost of a failed CMS migration is the expense of having to redo the work. If the migration is not executed correctly, your team may need to spend additional time and resources fixing errors and re-implementing content and features, resulting in increased development costs and lost productivity.
When you migrate your CMS, there’s always a chance that some data or content may not transfer correctly, which can impact the digital experience. This can include anything from broken links and images to lost data, which can affect your search engine rankings and user experience.
Furthermore, any data or content lost during the migration process can take considerable time to restore, delaying your digital launch and further increasing costs and downtime. Post-migration, you’ll lament content, integrations, or UI/UX components that were missed during the migration due to a lack of planning or knowledge.
Your business may face legal penalties or regulatory fines if personal or sensitive data is lost during the migration process. These costs can be high and have long-lasting effects on your business’s financial health and reputation.
You must also never underestimate the time it takes to migrate a website or host of websites. Your new CMS will enable you to offer better and faster customer experiences across more channels. Yet every day your migration is delayed is another day your business misses out on those higher conversion rates.
A migration project that takes too long or encounters several delays can result in missed opportunities for your business to implement new initiatives or capitalize on emerging trends.
For instance, if your business plans to launch a new product or service, a delayed CMS migration can lead to missed opportunities to promote and market the new offering. Similarly, if there are changes in customer behavior or market trends, a protracted migration project may mean that your business cannot quickly respond to these shifts, leading to missed opportunities for growth and revenue.
In addition, a delayed CMS migration can also impact your business’s ability to stay competitive. If your website is outdated or not functioning optimally, you may lose customers to competitors with better online experiences. A long migration project can also impact your team’s ability to focus on other critical projects and initiatives, resulting in missed opportunities for your business.
This extends to alienating your customers as well. If your migration doesn’t go as planned and your website has extended downtime, frustrated visitors may seek alternative solutions, leading to lost customers and revenue.

When it comes to CMS migration, assembling the right team is critical to a successful outcome. It must be a cross-functional team that includes stakeholders from different areas of your business, including your IT department, web development team, marketing team, and other relevant stakeholders.
Who should be included in the list of stakeholders? Here are a few considerations:
C-Suite: Authorizes the CMS migration and should be consulted at various project stages.
Project Manager: Oversees the entire migration process and ensures that all tasks are completed on time and within budget.
Content Strategist: Ensures that the new CMS supports the organization’s content strategy.
Solutions Architect: Designs and implements technical solutions and evaluates the migration process.
Developers: Tasked with creating content experiences using the CMS and will need to be consulted on key features.
Marketing Team: Tasked with creating and publishing content using the new CMS and will need to be consulted to ensure the right features are available.
End Users: Necessary to provide feedback and ensure the new system meets usability and functionality needs.
Legal Team: Ensures that the new CMS complies with relevant laws and regulations, such as data privacy laws.
System Integrators: Agencies and licensed experts familiar with the CMS, which may help your development team and architects with the implementation.
It’s also essential to ensure that your team has access to the right tools and resources. This may include project management software, collaboration tools, and access to any necessary third-party services, such as hosting providers or content delivery networks.
After you’ve assembled your migration team, it’s time to formulate your plan. Your migration plan should be detailed and include a clear timeline for the project, as well as a list of all the tasks that need to be completed. It should also include a risk assessment that outlines potential challenges and setbacks and strategies for addressing them.
Here you will establish the deadlines, milestones, and potential downtime and how to avoid or at least minimize it. You’ll also need to outline the risks involved, how to deter them, and plans for what to do if each occurs.
The plan should include a comprehensive list of all the data, content, and features that need to be migrated. Identifying customizations or third-party integrations that may impact the migration process is also important.
Next, you’ll need to identify your migration strategy. This may involve a phased approach, where you migrate different components of your website over a period of time, or a full-on approach, where you migrate everything at once. Ultimately, your migration strategy will depend on a variety of factors, including the complexity of your website and your business goals.
In addition to your migration strategy, you’ll need to develop a testing plan to ensure everything works correctly after the migration is complete. This should include both functional testing to ensure that all the features and functionality of your website are working correctly, and performance testing, to ensure that your website is performing well under different conditions. It’s also important to ensure that your team has a clear communication plan that includes regular updates and progress reports, as well as a system for addressing any issues that arise during the migration process.
The ease with which you can migrate to a new CMS will depend heavily on your starting point. Are you using a legacy or monolithic CMS? Or a headless CMS? Maybe you have no CMS?
Arguably the most simple of starting positions. If you don’t already have a CMS, such as if you’re a startup without an established web presence or if you’ve just undergone a merger and will be building a new digital experience from scratch, your content assets (if any) might be stored on a local database or might not have been created yet. Whatever the reason you don’t have an existing content management system, it does make things easier as there will be no pre-defined restrictions on what your team can do.
If you’re moving from a custom, legacy, monolithic, or even a traditional CMS, your migration process will look different than the other situations. With a legacy system, your content audit and content modeling process will need considerably more attention, as your existing content may be tightly coupled to your existing legacy CMS, which may have imposed restrictions or parameters within which your content exists.
You will need to analyze your existing content and its metadata, including its structure, organization, and relationship to other content, to ensure that it can be migrated to your new CMS.
In addition, when migrating from a legacy CMS, you will need to consider how to handle content that is no longer needed or is outdated. Archiving, deleting, and consolidating certain content may be necessary to streamline the migration process.
Unlike a traditional or legacy CMS, with a headless CMS, you can create content models that are removed from the presentation layer, as a headless CMS places no limits on how or where content needs to be displayed. This allows you to reuse content across multiple channels and means that content modeling and migration will require careful planning to ensure that the content models are compatible with the new headless CMS.
In your new headless CMS, you are free to architect your content as you like. But to do that, you will need to identify exactly where your existing content lies before creating these new models in conjunction with your team of developers or your system integration agency.
Something else which heavily impacts any CMS migration is how compatible your chosen CMS is with the other tools in the technology stack.
Every business uses various third-party tools and integrations, such as analytics tools, marketing automation platforms, and CRM systems. Before migrating to a new CMS, ensure that it’s compatible with all of these tools and other potential new software solutions that might be added to your technology stack.
What do you do about the technology you are currently using?
Start by making an audit of existing technologies. Some will, of course, continue to be used as part of the tech stack, while others may be replaced and rendered unnecessary depending on the functionality of your existing CMS.
If you need to integrate your CMS with existing systems, using non-headless infrastructure needs more thought, and integrations are far more time-consuming. Hygraph solves this issue with a backend-agnostic API-first solution. Our federated content platform is built using MACH architecture, which follows the principles of composability and enables more seamless integrations with various tools in the technology stack that follow similar principles with the help of APIs.
Hygraph also provides a Content Federation capability that pulls content and external data from other systems to the Hygraph API without forcing you to migrate that content. For example, content such as product or pricing data can be pulled from an eCommerce system. Buyer history and demographic details could also be drawn from a customer data platform to create new content experiences in Hygraph. This improves the CMS migration process as businesses can remove the high development time and total ownership cost when integrating multiple APIs.
We also offer integrations with tools like Frontastic and Algolia and more ready to use. We’re always open to building new and more nuanced integrations whenever our customers need them. Our new app SDK enables you to add new functionality, connect to external systems, automate workflows, and more while our native GraphQL API allows you to work with preferred frameworks such as Next.js, Remix, and others.
Arguably the biggest challenge and most costly aspect of a CMS migration (both in time and financial resources) is content and data management.
Those using legacy systems will need to audit and map exactly where their content lives within their CMS. That’s because, over time, many legacy systems tend to suffer from content silos since content was originally designed for use on one channel.
For example, in your legacy CMS, your blog content may have been located in one section with a specified template for that type of content. Meanwhile, content for a mobile application would be located in another area with similar restrictions or even a completely different CMS. This separation may have been fine when you were using that particular CMS, but it may not make sense when migrating to a new content platform with a different structure, such as a headless CMS.
Once the audit has been completed, you’ll want to build content models that your existing content can fit into and that work in tandem with your website(s) new UI/UX.
A content audit analyzes your content assets to inventory and evaluates how each asset fits into your content strategy. It can help determine which content assets should be migrated and how to create the appropriate content models for the new CMS.
Why do this? It provides an ideal scenario of what your content looks like for the end-user and post-migration. Once you’ve looked at what you have, along with what you want to have, you can identify the following:
Content that you can migrate to the new CMS in bulk without editing.
Content that you want to move to your new CMS, which will need to be edited along the way.
Content that needs to be entirely replaced.
Content that you no longer want to keep.
And finally, all the gaps that need to be filled in.
After completing your content audit, you can begin to model the content that will be migrated. Content modeling involves creating a logical taxonomy structure for the content you create and distribute online.
A content model enables teams to sync their ideas of the goals behind the content and ensure that when that content comes to fruition, it has all of the elements discussed in planning. It also allows you to take that ideal scenario from earlier and start working backward, with your existing content as a starting point.
Key considerations when content modeling Content modeling is usually a 4-step process.
Establishing the intent of the content by deciding what purpose it needs to solve in the short term and leaving room for extensibility in the mid-to-long term when that content could serve multiple purposes.
Analyzing the requirements and determining what content types would be needed.
Identify the structure of this content model and how many other content types or models need to be referenced.
Developing the content model with a combination of fields that fulfill the intent of that content.
However, when performing content modeling based on a former system, you need to take into account the pre-existing requirements. The key is maintaining the content management experience post-migration, and the choice of CMS can play an important role in this.
Hygraph offers a very flexible content modeling approach that separates it from other headless content management systems. Some of the features include:
Sortable Relations: Sortable relations (also called GraphQL Union Types) are relations where developers can build a highly flexible basic model, and content editors have the power to make changes to the presentation without changing the inherent structure.
Management SDK: The Hygraph Management SDK allows teams to create schema migrations using Javascript and apply those changes programmatically.
Mutations API: A project endpoint exposes GraphQL mutations you can use to modify the contents of your project. The mutations API allows you to interact with content outside the Hygraph UI using GraphQL, which opens up the possibility of importing the content to a new system.
Another factor to consider is making schema improvements before the data migration. Some people believe it is easier to make schema improvements once you dump all the content into the CMS and then do a content audit, followed by a schema audit. However, Hygraph offers a Schema Builder feature that gives developers, content creators, and content managers easy-to-use tools to create models or templates for various content needs.
Again, Content Federation plays a vital role in content and data migration. It allows you to bring content from legacy systems that can’t be easily migrated to a new content repository and pulls it to the Hygraph API, streamlining the process for developers.
Now that you know your technology requirements and content models, it’s time to execute - backup your content and migrate to your new CMS. The migration process can happen quickly as migration tools are often available to make the process fast and smooth. However, in some cases, manual content migration may be necessary, depending on the content volume or complexity of content structures.
The initial migration can also be performed in a test environment to ensure everything has been set up correctly and to catch any potential errors before things get too far.
We’re almost at the end of the migration process and ready to adopt a new content platform. So what other considerations do we need to make?
The correct permissions must be set up for the different users in your organization. This ensures that everyone has the right level of access to the system and that sensitive data is not compromised.
Hygraph offers granular permissions, allowing teams to create custom roles for internal and external users and tokens that give more control over who has access to what content and their ability to interact with it. This is particularly useful for companies that want to adopt a multi-tenant architecture.
When the online gaming convention Gamescom needed a platform that could handle extremely high traffic peaks and provide a robust content repository to manage content from over 200 contributors, they turned to Hygraph. They could set up several custom roles for external users with granular permissions, and create a multi-tenant infrastructure that provided custom access to external editors from companies like Microsoft Xbox, Ubisoft, and BANDAI NAMCO, to add their content into Hygraph.

Find out whether your CMS vendors offer onboarding or training programs to help get your team upskilled. The right training programs can equip your team to use the new system. This is particularly important if the new CMS is different from what your team was accustomed to and to ensure that everyone understands the new system and is proficient in using it.
Before going to production, a testing phase should occur to ensure that the new system functions as expected and any issues are resolved before going live. Even after the system is up and running, continuous improvement and development processes will be needed to ensure that any future changes or updates are rolled out smoothly.
Working closely with your new CMS vendor is also important, as you might need support during the post-migration phase. A good CMS vendor will provide you with the support and resources you need to ensure a successful migration, including documentation and training resources. Working with your vendor will also ensure that you stay up to date with the latest features and improvements to the system.
Hygraph offers extensive documentation as well as the SDK, APIs, and UI to make it easier to create and manage your schema and content. This makes migrating your content and data assets to Hygraph more straightforward than doing it alone.
After you’ve implemented your new CMS, introduced appropriate roles and permission hierarchies to ensure that everyone who needs to access it can do so without issues, and trained your staff on how to use the new CMS, there are still a few crucial things that need to be done, and all of them relate to testing.
During a CMS migration, it’s not uncommon for a few things to get disrupted, so you need to test to ensure that everything has been transferred correctly and to find any issues that might negatively affect you down the road. Here are some of the things to check during your testing period:
Content and data accuracy: Verify that all content has been accurately migrated, that the metadata is correct and that all assets are in the right place.
Ensure SEO integrity: Ensure all pages and content have the same or better SEO ranking after the migration. Check the URLs, titles, meta tags, and other elements to ensure they meet SEO best practices.
Check for broken links: Run a broken link checker to ensure that all internal and external links are still valid. This helps avoid any negative impact on your SEO rankings or user experience.
Monitor and watch for issues: After the migration, keep an eye on any issues or problems that might arise and track key performance indicators (KPIs) to compare with the previous system. This helps to identify any areas for improvement and make necessary adjustments.
After everything has been tested and verified, it’s time to enjoy the benefits of your new CMS. However, don’t forget to monitor the impact on performance and how you can keep improving the digital experience.
You now have a clear understanding of what it takes to migrate to a new content management system and its various costs. But what is the true financial impact you’ll have to deal with?
We can’t provide a definitive answer because there are just too many variables, but we can offer some general guidelines on coming up with a number for yourself. Here are some of the things to consider:
New platform costs: This includes licensing costs and service level agreements.
Hosting: Dependent on whether your CMS will be hosted in the cloud, self-hosted, or a hybrid deployment.
Business or project-specific criteria: Each CMS offers different pricing and criteria based on factors such as the number of content entries, number of locales, number of API requests, bandwidth, content assets, and more which will be unique to your organization.
Total cost of ownership: If you’re choosing a platform that's not backend agnostic, TCO becomes a stumbling block as now you need to think about how you can pull together several different sources of data and multiple integrations.
Personnel: CMSs will have different prices depending on your required seats. During the migration process, you might also need a team of developers to assist you, as well as specialized system integrators.
Training: If your current developers and content editors aren’t familiar with the new technology, additional training or hiring may be required.
Contingencies: Even after you’ve assessed everything to the tee, you’ll need to include a buffer of around 15-20% for contingencies.
There are numerous factors to take into account when getting ready to perform a CMS migration, from the potential missed opportunities to the platform you’re moving from to how compatible your technology is with the new CMS and how you will manage your content and data assets during the migration.
However, being aware of these additional factors can get you closer to an accurate estimate that allows you to budget accordingly instead of just relying on an initial forecast based on the size of your organization.

You must also never underestimate the time it takes to migrate a website or host of websites. Your new CMS will enable you to offer better and faster customer experiences across more channels. Yet every day your migration is delayed is another day your business misses out on those higher conversion rates.
A migration project that takes too long or encounters several delays can result in missed opportunities for your business to implement new initiatives or capitalize on emerging trends.
For instance, if your business plans to launch a new product or service, a delayed CMS migration can lead to missed opportunities to promote and market the new offering. Similarly, if there are changes in customer behavior or market trends, a protracted migration project may mean that your business cannot quickly respond to these shifts, leading to missed opportunities for growth and revenue.
In addition, a delayed CMS migration can also impact your business’s ability to stay competitive. If your website is outdated or not functioning optimally, you may lose customers to competitors with better online experiences. A long migration project can also impact your team’s ability to focus on other critical projects and initiatives, resulting in missed opportunities for your business.
This extends to alienating your customers as well. If your migration doesn’t go as planned and your website has extended downtime, frustrated visitors may seek alternative solutions, leading to lost customers and revenue.

When it comes to CMS migration, assembling the right team is critical to a successful outcome. It must be a cross-functional team that includes stakeholders from different areas of your business, including your IT department, web development team, marketing team, and other relevant stakeholders.
Who should be included in the list of stakeholders? Here are a few considerations:
C-Suite: Authorizes the CMS migration and should be consulted at various project stages.
Project Manager: Oversees the entire migration process and ensures that all tasks are completed on time and within budget.
Content Strategist: Ensures that the new CMS supports the organization’s content strategy.
Solutions Architect: Designs and implements technical solutions and evaluates the migration process.
Developers: Tasked with creating content experiences using the CMS and will need to be consulted on key features.
Marketing Team: Tasked with creating and publishing content using the new CMS and will need to be consulted to ensure the right features are available.
End Users: Necessary to provide feedback and ensure the new system meets usability and functionality needs.
Legal Team: Ensures that the new CMS complies with relevant laws and regulations, such as data privacy laws.
System Integrators: Agencies and licensed experts familiar with the CMS, which may help your development team and architects with the implementation.
It’s also essential to ensure that your team has access to the right tools and resources. This may include project management software, collaboration tools, and access to any necessary third-party services, such as hosting providers or content delivery networks.
After you’ve assembled your migration team, it’s time to formulate your plan. Your migration plan should be detailed and include a clear timeline for the project, as well as a list of all the tasks that need to be completed. It should also include a risk assessment that outlines potential challenges and setbacks and strategies for addressing them.
Here you will establish the deadlines, milestones, and potential downtime and how to avoid or at least minimize it. You’ll also need to outline the risks involved, how to deter them, and plans for what to do if each occurs.
The plan should include a comprehensive list of all the data, content, and features that need to be migrated. Identifying customizations or third-party integrations that may impact the migration process is also important.
Next, you’ll need to identify your migration strategy. This may involve a phased approach, where you migrate different components of your website over a period of time, or a full-on approach, where you migrate everything at once. Ultimately, your migration strategy will depend on a variety of factors, including the complexity of your website and your business goals.
In addition to your migration strategy, you’ll need to develop a testing plan to ensure everything works correctly after the migration is complete. This should include both functional testing to ensure that all the features and functionality of your website are working correctly, and performance testing, to ensure that your website is performing well under different conditions. It’s also important to ensure that your team has a clear communication plan that includes regular updates and progress reports, as well as a system for addressing any issues that arise during the migration process.
The ease with which you can migrate to a new CMS will depend heavily on your starting point. Are you using a legacy or monolithic CMS? Or a headless CMS? Maybe you have no CMS?
Arguably the most simple of starting positions. If you don’t already have a CMS, such as if you’re a startup without an established web presence or if you’ve just undergone a merger and will be building a new digital experience from scratch, your content assets (if any) might be stored on a local database or might not have been created yet. Whatever the reason you don’t have an existing content management system, it does make things easier as there will be no pre-defined restrictions on what your team can do.
If you’re moving from a custom, legacy, monolithic, or even a traditional CMS, your migration process will look different than the other situations. With a legacy system, your content audit and content modeling process will need considerably more attention, as your existing content may be tightly coupled to your existing legacy CMS, which may have imposed restrictions or parameters within which your content exists.
You will need to analyze your existing content and its metadata, including its structure, organization, and relationship to other content, to ensure that it can be migrated to your new CMS.
In addition, when migrating from a legacy CMS, you will need to consider how to handle content that is no longer needed or is outdated. Archiving, deleting, and consolidating certain content may be necessary to streamline the migration process.
Unlike a traditional or legacy CMS, with a headless CMS, you can create content models that are removed from the presentation layer, as a headless CMS places no limits on how or where content needs to be displayed. This allows you to reuse content across multiple channels and means that content modeling and migration will require careful planning to ensure that the content models are compatible with the new headless CMS.
In your new headless CMS, you are free to architect your content as you like. But to do that, you will need to identify exactly where your existing content lies before creating these new models in conjunction with your team of developers or your system integration agency.
Something else which heavily impacts any CMS migration is how compatible your chosen CMS is with the other tools in the technology stack.
Every business uses various third-party tools and integrations, such as analytics tools, marketing automation platforms, and CRM systems. Before migrating to a new CMS, ensure that it’s compatible with all of these tools and other potential new software solutions that might be added to your technology stack.
What do you do about the technology you are currently using?
Start by making an audit of existing technologies. Some will, of course, continue to be used as part of the tech stack, while others may be replaced and rendered unnecessary depending on the functionality of your existing CMS.
If you need to integrate your CMS with existing systems, using non-headless infrastructure needs more thought, and integrations are far more time-consuming. Hygraph solves this issue with a backend-agnostic API-first solution. Our federated content platform is built using MACH architecture, which follows the principles of composability and enables more seamless integrations with various tools in the technology stack that follow similar principles with the help of APIs.
Hygraph also provides a Content Federation capability that pulls content and external data from other systems to the Hygraph API without forcing you to migrate that content. For example, content such as product or pricing data can be pulled from an eCommerce system. Buyer history and demographic details could also be drawn from a customer data platform to create new content experiences in Hygraph. This improves the CMS migration process as businesses can remove the high development time and total ownership cost when integrating multiple APIs.
We also offer integrations with tools like Frontastic and Algolia and more ready to use. We’re always open to building new and more nuanced integrations whenever our customers need them. Our new app SDK enables you to add new functionality, connect to external systems, automate workflows, and more while our native GraphQL API allows you to work with preferred frameworks such as Next.js, Remix, and others.
Arguably the biggest challenge and most costly aspect of a CMS migration (both in time and financial resources) is content and data management.
Those using legacy systems will need to audit and map exactly where their content lives within their CMS. That’s because, over time, many legacy systems tend to suffer from content silos since content was originally designed for use on one channel.
For example, in your legacy CMS, your blog content may have been located in one section with a specified template for that type of content. Meanwhile, content for a mobile application would be located in another area with similar restrictions or even a completely different CMS. This separation may have been fine when you were using that particular CMS, but it may not make sense when migrating to a new content platform with a different structure, such as a headless CMS.
Once the audit has been completed, you’ll want to build content models that your existing content can fit into and that work in tandem with your website(s) new UI/UX.
A content audit analyzes your content assets to inventory and evaluates how each asset fits into your content strategy. It can help determine which content assets should be migrated and how to create the appropriate content models for the new CMS.
Why do this? It provides an ideal scenario of what your content looks like for the end-user and post-migration. Once you’ve looked at what you have, along with what you want to have, you can identify the following:
Content that you can migrate to the new CMS in bulk without editing.
Content that you want to move to your new CMS, which will need to be edited along the way.
Content that needs to be entirely replaced.
Content that you no longer want to keep.
And finally, all the gaps that need to be filled in.
After completing your content audit, you can begin to model the content that will be migrated. Content modeling involves creating a logical taxonomy structure for the content you create and distribute online.
A content model enables teams to sync their ideas of the goals behind the content and ensure that when that content comes to fruition, it has all of the elements discussed in planning. It also allows you to take that ideal scenario from earlier and start working backward, with your existing content as a starting point.
Key considerations when content modeling Content modeling is usually a 4-step process.
Establishing the intent of the content by deciding what purpose it needs to solve in the short term and leaving room for extensibility in the mid-to-long term when that content could serve multiple purposes.
Analyzing the requirements and determining what content types would be needed.
Identify the structure of this content model and how many other content types or models need to be referenced.
Developing the content model with a combination of fields that fulfill the intent of that content.
However, when performing content modeling based on a former system, you need to take into account the pre-existing requirements. The key is maintaining the content management experience post-migration, and the choice of CMS can play an important role in this.
Hygraph offers a very flexible content modeling approach that separates it from other headless content management systems. Some of the features include:
Sortable Relations: Sortable relations (also called GraphQL Union Types) are relations where developers can build a highly flexible basic model, and content editors have the power to make changes to the presentation without changing the inherent structure.
Management SDK: The Hygraph Management SDK allows teams to create schema migrations using Javascript and apply those changes programmatically.
Mutations API: A project endpoint exposes GraphQL mutations you can use to modify the contents of your project. The mutations API allows you to interact with content outside the Hygraph UI using GraphQL, which opens up the possibility of importing the content to a new system.
Another factor to consider is making schema improvements before the data migration. Some people believe it is easier to make schema improvements once you dump all the content into the CMS and then do a content audit, followed by a schema audit. However, Hygraph offers a Schema Builder feature that gives developers, content creators, and content managers easy-to-use tools to create models or templates for various content needs.
Again, Content Federation plays a vital role in content and data migration. It allows you to bring content from legacy systems that can’t be easily migrated to a new content repository and pulls it to the Hygraph API, streamlining the process for developers.
Now that you know your technology requirements and content models, it’s time to execute - backup your content and migrate to your new CMS. The migration process can happen quickly as migration tools are often available to make the process fast and smooth. However, in some cases, manual content migration may be necessary, depending on the content volume or complexity of content structures.
The initial migration can also be performed in a test environment to ensure everything has been set up correctly and to catch any potential errors before things get too far.
We’re almost at the end of the migration process and ready to adopt a new content platform. So what other considerations do we need to make?
The correct permissions must be set up for the different users in your organization. This ensures that everyone has the right level of access to the system and that sensitive data is not compromised.
Hygraph offers granular permissions, allowing teams to create custom roles for internal and external users and tokens that give more control over who has access to what content and their ability to interact with it. This is particularly useful for companies that want to adopt a multi-tenant architecture.
When the online gaming convention Gamescom needed a platform that could handle extremely high traffic peaks and provide a robust content repository to manage content from over 200 contributors, they turned to Hygraph. They could set up several custom roles for external users with granular permissions, and create a multi-tenant infrastructure that provided custom access to external editors from companies like Microsoft Xbox, Ubisoft, and BANDAI NAMCO, to add their content into Hygraph.

Find out whether your CMS vendors offer onboarding or training programs to help get your team upskilled. The right training programs can equip your team to use the new system. This is particularly important if the new CMS is different from what your team was accustomed to and to ensure that everyone understands the new system and is proficient in using it.
Before going to production, a testing phase should occur to ensure that the new system functions as expected and any issues are resolved before going live. Even after the system is up and running, continuous improvement and development processes will be needed to ensure that any future changes or updates are rolled out smoothly.
Working closely with your new CMS vendor is also important, as you might need support during the post-migration phase. A good CMS vendor will provide you with the support and resources you need to ensure a successful migration, including documentation and training resources. Working with your vendor will also ensure that you stay up to date with the latest features and improvements to the system.
Hygraph offers extensive documentation as well as the SDK, APIs, and UI to make it easier to create and manage your schema and content. This makes migrating your content and data assets to Hygraph more straightforward than doing it alone.
After you’ve implemented your new CMS, introduced appropriate roles and permission hierarchies to ensure that everyone who needs to access it can do so without issues, and trained your staff on how to use the new CMS, there are still a few crucial things that need to be done, and all of them relate to testing.
During a CMS migration, it’s not uncommon for a few things to get disrupted, so you need to test to ensure that everything has been transferred correctly and to find any issues that might negatively affect you down the road. Here are some of the things to check during your testing period:
Content and data accuracy: Verify that all content has been accurately migrated, that the metadata is correct and that all assets are in the right place.
Ensure SEO integrity: Ensure all pages and content have the same or better SEO ranking after the migration. Check the URLs, titles, meta tags, and other elements to ensure they meet SEO best practices.
Check for broken links: Run a broken link checker to ensure that all internal and external links are still valid. This helps avoid any negative impact on your SEO rankings or user experience.
Monitor and watch for issues: After the migration, keep an eye on any issues or problems that might arise and track key performance indicators (KPIs) to compare with the previous system. This helps to identify any areas for improvement and make necessary adjustments.
After everything has been tested and verified, it’s time to enjoy the benefits of your new CMS. However, don’t forget to monitor the impact on performance and how you can keep improving the digital experience.
You now have a clear understanding of what it takes to migrate to a new content management system and its various costs. But what is the true financial impact you’ll have to deal with?
We can’t provide a definitive answer because there are just too many variables, but we can offer some general guidelines on coming up with a number for yourself. Here are some of the things to consider:
New platform costs: This includes licensing costs and service level agreements.
Hosting: Dependent on whether your CMS will be hosted in the cloud, self-hosted, or a hybrid deployment.
Business or project-specific criteria: Each CMS offers different pricing and criteria based on factors such as the number of content entries, number of locales, number of API requests, bandwidth, content assets, and more which will be unique to your organization.
Total cost of ownership: If you’re choosing a platform that's not backend agnostic, TCO becomes a stumbling block as now you need to think about how you can pull together several different sources of data and multiple integrations.
Personnel: CMSs will have different prices depending on your required seats. During the migration process, you might also need a team of developers to assist you, as well as specialized system integrators.
Training: If your current developers and content editors aren’t familiar with the new technology, additional training or hiring may be required.
Contingencies: Even after you’ve assessed everything to the tee, you’ll need to include a buffer of around 15-20% for contingencies.
There are numerous factors to take into account when getting ready to perform a CMS migration, from the potential missed opportunities to the platform you’re moving from to how compatible your technology is with the new CMS and how you will manage your content and data assets during the migration.
However, being aware of these additional factors can get you closer to an accurate estimate that allows you to budget accordingly instead of just relying on an initial forecast based on the size of your organization.
