Upgrade from Joomla 3 to 4

Joomla 4 is the next major release of Joomla.

Joomla 3.10 was released parallel to Joomla 4.0 as the last version of Joomla 3. Joomla 3.10 a bridge between the two major series to facilitate the transition to the next major release. The Joomla update component in version 3.10 is equipped with a new function, the "Pre-update Checker". This helps with the mini-migration process. As soon as the website is updated to 3.10, the Pre-Update Checker can be used to check the compatibility of the PHP and SQL options, settings and the extensions used with Joomla 4.0. This check is absolutely necessary! The upgrade to Joomla 4 should only be done if the compatibility is ensured.

Joomla 3.10 will continue to be supported for 2 years (August, 2023). This gives you the time you need to plan a migration to Joomla 4 and update extensions to become compatible with Joomla 4.0.
