How to migrate your system from Joomla version 3.10.xx with JoomGallery 3.6.2 to Joomla 4 with JoomGallery 4.
Don't uninstall your old JoomGallery, because this will delete all your JoomGallery data from your system. Be sure that your Joomla Version has the actual status 3.10.12 and your JoomGallery has the actual status 3.6.2. If not, upgrade your systems. It is a good idea to upgrade all other components to the actual state in version 3.x.x before you start the upgrade to versions 4..
Backup your system. For instance, run Akeeba-Backup with latest versions.
