JLex Transfer is a useful Joomla tool for transferring Joomla 3.x data to Joomla 4.x. This is useful if you want to duplicate the data of the old site on the new one. You can easily transfer local files (videos, music, photos), categories and content, user list, personal profile and group data. You can also copy the settings and configuration of any module, regardless of vendor. To migrate, you need to install the component on both sites.
