This is the process to upgrade any of the Regular Labs Extensions:

  1. First, make sure that your Joomla 3 site is updated to the latest Joomla 3.10 release
  2. On Joomla 3.10, update all the installed Regular Labs Extensions to their latest version
  3. Upgrade your Joomla 3.10 site to Joomla 4
  4. Upgrade the PHP version on your server to PHP 8.1 or higher
  5. Reinstall the latest versions of all the Regular Labs extensions. This will upgrade the extensions to their Joomla 4 counterpart.
