Like extensions, your Joomla 3 template might not work with Joomla 4. Check if an updated version is available. If not, consider using a new template.

A Joomla update check will tell you which extensions are compatible and which ones need to be updated. This step can save you from potential headaches down the line.

Disable Incompatible Extensions

If you find any incompatible extensions during the update check, unpublish them. Do not uninstall them, as you may lose important data.

Disable System Plugins

Before you start the upgrade, disable all system plugins. This will ensure they don't interfere with the process.

Ensure Your Server Meets Joomla 4 Requirements

Joomla 4 requires PHP 7.2 or higher. Make sure your server meets this requirement to avoid any compatibility issues.

Test Before Going Live

Once you've upgraded, don't push your website live right away. Test thoroughly to ensure everything is working as expected.
