Joomla recently released their newest version, Joomla 4! This comes with many improvements as well as a total redesign. If like us you’re excited to upgrade to this new version and start messing around with the new features, it’s important to first take a second to make sure your site is ready to migrate. In this blog, we are going to share some tips to make sure you have a safe migration for your site. 

While migrating from Joomla 3.10.X to Joomla 4 is considered a minor migration, the Joomla Core Extensions will be updated through the “one-click update” process. If you have any third-party extensions it is necessary to verify case by case, if these extensions are compatible with Joomla 4.

Before Migrating to Joomla 4

  • To begin with, it is always wise to keep a backup copy, before these types of updates.
  • Update your website to version 3.10.X
  • A2Hosting complies with the necessary requirements to run Joomla 4, for this reason, feel sure that your server will work without problems.
  • Make a summary of the third-party extensions that you use, plugins, modules, components, languages, and templates.
  • In the summary of third-party extensions, previously created, notate which most used, barely used, and not used at all. 
  • Use the Pre-Update Check component, which is available in Joomla 3.10.X, to determine if the extensions you have installed are compatible with Joomla 4.

Pre Update Check

  • The opportunity to migrate to this newest version gives you a great chance to clean up your site. Take this time to look at your site Categories to determine if they are necessary or not. This way you only end up migrating content you truly need.
  • If you are using the Protostar template, you will no longer be able to use it in Joomla 4, it will be removed after migration to Joomla 4. As a substitute, Joomla presents Cassiopeia Template. 

Cassiopeia Template

  • If you have purchased an alternative template, make sure it is compatible with Joomla 4 before you update.
