Joomla Website Backup
Backing up your website is crucial to safeguard your data in case anything goes wrong during the upgrade process. The best way to back up your site is using a backup extension (like Akeeba). Do not miss this step if you don’t want to lose the Joomla site data!
Pre-Update Check
Since Joomla 3.10 includes a pre-update check, you can verify the compatibility of the extensions and templates you use with Joomla 4. Thus, when using this function, you can quickly identify which extensions are incompatible with Joomla 4. After that, decide whether to update, remove, or unpublish it. This step will ensure that you can upgrade Joomla 3 to Joomla 4 without any trouble during the upgrading process.
