If you operate Edjet LMS Server which version is unsupported to do the automatic upgrade, you can migrate the data using ad-hoc procedures.
Migrate User and User groups stored in SQL database using SQL scripts.
Supported version/s - old installation: 3.9.5, new installation: 6.4.23
Do the backup before you start.
Use any capable SQL manager - you can download one here: https://dbeaver.io
To ensure consistent database state, especially in references using "user_id", avoid any usage of the system between LMS upgrade/migration and this steps.
Steps:
Solution: Some user's folders (records named "user_ID", where ID is ID of the user) in "media_library" table are having user_id = null. Make sure to add the ID, or repeat the process of upgrade/migration with a consistent database state.
Copy LMS folder "repository" containing all user files - Media Library uploads from old LMS installation to new.
Supported version/s - old installation: 3.9.5 or above, new installation: 3.9.5 or above
Do the backup before you start.
