When does support for Craft CMS 4 end?

Full support for Craft CMS 4 ended in April this year. This means there are now no further feature updates of bug fixes. You may encounter compatibility issues or find bugs more difficult to fix. In April 2026 Craft CMS security support will end. Upgrading to Craft CMS 5 will minimise security risks. 

While Craft CMS 4 introduced major performance enhancements, especially for content editing, along with ongoing security updates. Craft CMS 5 takes it a step further with significant improvements to content modelling, a refined user interface, and new features like two-factor authentication. It’s the latest and most advanced version, offering greater flexibility and control over your website.

Why upgrade to Craft CMS 5?

• Craft CMS 4 and older versions are no longer receiving updates. Craft CMS 3 and older versions no longer receive security patches.
• When a system doesn't receive security patches it means your site could be at risk. This will be the case for Craft CMS 4 from April 2026.
• Plugins running on Craft 4 and below will also stop receiving updates, potentially leaving your site vulnerable.
• Upgrading to Craft CMS 5 will not only protect your website but also provide you with the latest features and improvements.

What does the upgrade process involve?

If you're still on Craft CMS 3, upgrading to Craft CMS 5 involves a two-step process: first, upgrading to Craft CMS 4, then moving to Craft CMS 5. 

Here’s what you can expect when working with us:

• Core Functionality Update: We’ll upgrade your site’s core functionality to be fully compatible with Craft CMS 5x.
• Plugin and Module Upgrades: All plugins and modules will be updated to work seamlessly with the new version.
• Replacing Outdated Plugins: We’ll replace any plugins or modules that cannot be upgraded.
• Custom Code Rewriting: If any of your custom code is not compatible with Craft CMS 5, we’ll rewrite it to ensure smooth operation.
• Data Transfer: We’ll update your newsletter system data and other important site information to ensure nothing is lost.
• Testing and Quality Assurance: Rigorous testing will be carried out to ensure your site performs perfectly after the upgrade.
• Seamless Deployment: Once everything is in place, we’ll release the upgraded site to live, with minimal disruption to your operations.
