I have totally messed up with my server, now I need to migrate configuration with users and mailboxes to the new one.
Few months ago upgraded server to 22.04 (Yup, I saw that this is unsupported and shouldn’t do like this), mail was working so I left it as is, later saw that roundcube is not working, but I do not use it often.
Now I decided to do a normal migration to new server, but after upgrade python stopped working as it should, unable to run backup, ssl scripts, etc.
Tried to fix that python issue, and at some point taught that maybe reinstall of python will help, after removal of python nothing is working anymore even no network.
Is it possible somehow to migrate configuration, users, mailboxes to new server without backup?
There is a backup few months old before upgrade, but I don’t want to loose all emails that was sent and received after that backup.
