The Ultimate Guide: Migrating Your Website to a New CMS

In today's fast-paced online world, it's crucial to keep your website and apps up-to-date. And when your digital presence is in dire need to keep up with the latest user needs and tech trends, switching to a new CMS might just be the best move.

However, there’s no denying it; CMS migration can be painful. And the harsh reality is, for more companies with legacy content management systems like Drupal, Joomla and WordPress, a CMS migration isn’t just a one-off annoyance, it’s an ongoing struggle. While a move to migrate can be daunting, with the right approach, it can boost your digital presence and strategy. 

Understanding Website Migrations and CMS Migrations

A CMS migration involves moving a website or even an entire digital presence from one CMS provider to another. Contrary to popular misconception, a CMS migration is not equivalent to a website redesign. While redesigning focuses on aesthetics, CMS migration enhances core functionalities, features, and overall user experiences.

Types of Website Migrations

Migrations can vary based on the scale and nature. They can range from full website migrations, where the entire digital presence is shifted, to partial migrations, where only certain components or sections of a site are moved.

Reasons Why You Might Need to Migrate Your Website to a New CMS

Why would an organization want to take on such a mammoth task, you ask? Well, here are the reasons and motivations we encounter regularly:

  • Issues with website speed.

  • High server downtime.

  • Inability to handle traffic spikes.

  • Outdated features.

  • Limited customization.

  • Limited content distribution capabilities, especially in cases where the existing CMS lacks headless content management functionality.

Step-by-Step Guide for a Website Migration

The process of migrating to a new CMS can be somewhat tricky, especially when you are shifting large amounts of data and content. Since every CMS migration is unique, here are some best practices to follow:

Hire a CMS Migration Project Manager: In any major project, having a central point of coordination is crucial. Hire a dedicated person who can keep track of milestones as well as streamline the migration process, monitor milestones, and ensure communication among all parties.

Utilize automated tools: For vast content repositories, automation is the best route because manual migration can become tedious and error-prone. Custom scripts or software can assist in this - especially for migrations involving large databases.

Audit your content: Before any changes, it’s important to understand how it's currently managed. This means deep dive into how your content functions on the current CMS and how it is organized.

Develop a migration strategy: Not all content might be relevant or necessary to migrate. Identify which content needs migration and which can be left behind. By migrating only valuable, pertinent content, you can optimize storage and management in the new system.

Make a clear content model: Migrating to a new CMS can be a golden opportunity to reevaluate how your content is structured and lay out a clearer organizational framework for your content. Effectively organize content relationships, hierarchies and structures.

Run post-migration tests: Once the migration is complete, it's vital to ensure everything has transferred correctly and is functioning optimally. Run a series of tests to check the responsiveness of the migrated content across various platforms and devices.

Addressing Post-Migration Tasks 

Common Website Migration Mistakes And How To Avoid Them

Naturally, the Zesty.io team has seen our fair share of migrations. Some website migrations go better than others. So we thought we’d put together a list of things to do (or not) that will help your next CMS migration go smoothly:

  • Back Up Your Current Site

Ensure that you are backing up your current site and database regularly will be useful in the event of a migration, so that in case something unprecedented goes wrong, you still have all of the original files and content. 

  • Keep Your Domain

If you have built equity in your domain, it may be more helpful to keep it than to replatform and change it. If you’re changing domain URLs, consult with an SEO agency prior to the migration, as there could be devastating effects. 

  • Don’t Duplicate Your Content

Duplicating content will result in severe penalties by Google because Google assumes that any copied content on the web is plagiarism. Sometimes, when migrating a site, content can accidentally be cloned. If you publish a site with cloned content, you may jeopardize your own site. 

  • Vet Your Professionals

If you’re hiring a team to help you with your migration, be sure to use a partner from your new platform’s Certified Partner Network. Using someone from this network typically guarantees that your migration will go smoothly, and if not, usually the platform will help you if your certified partner cannot. Choosing not to use a certified partner is a little bit like the wild west, and may cause more problems than you originally had. 

  • Cushion Your Timeline

Setting a timeline is always tricky when planning a content management re-platforming. First, make a CMS Migration Checklist of the things to be done. Then, estimate the timeline for each action item. After creating that timeline, be sure to cushion each action item by a few days to a week or so, depending on the item and how many resources you’ll be able to use to complete that action item. 

  • Secure Your Site

If your website doesn’t have https:// in the URL, it’s insecure, and Google is penalizing those sites for not being secure. While it’s important to turn on HTTPS, this causes a major change. 

Website Migration Tools and Resources

While tools like CMS2CMS are handy for automated migration, platforms like Zesty.io offer a plethora of tools to ease the migration journey. Their drag-and-drop code importer, Google WebMaster Integration, and CSV import features streamline the process, minimizing hiccups.

Selecting the ideal CMS goes beyond just features. It’s about future-proofing your digital presence. Zesty.io stands out, offering built-in custom JSON feed functionality, multi-site support, and an independent presentation layer.

Frequently Asked Questions

Does changing CMS affect SEO?

Yes, it absolutely can. When you're thinking about moving to a different CMS, there's a lot at stake for your site's SEO. One important piece of advice is to try to keep your URL structures the same if you can. And if you've got URLs that are changing, make sure you put in 301 redirects from the old ones to the new ones. Tip: Be sure to watch out for duplicating content. That's a quick way to get on the bad side of search engines.

Are there any risks of data loss during a CMS migration?

Yes, hence the importance of backing up all data before starting the process.

How long does a CMS migration typically take?

This depends on the website's size and complexity. It can range from a few days to weeks or even months. Zesty.io can give you a free estimation of your migration time if you contact us here.

Can I perform a CMS migration on my own, or do I need professional help?

While it's possible to do it on your own, seeking professional help, especially for large-scale migrations, is recommended.
