I don’t know where the Playlists were backup up exactly. I think on the old server drive.
The setup of the new server was done by the developer of the new server (who has done this many time without losing playlists from Roon), so I can only assume that he would have followed the right protocol not to lose my playlists.
Btw, this happened to me before (lost all playlists)-- I don’t recall the exact circumstance.
But again, my Roon Playlist was on Auto Backup.
Shouldn’t there be some kind of prompted migration process when switching cores?
And again, please explain why my Library is intact with the switch but the Playlists are vanished (apparently)? Are they saved differently?
If a playlist was made in Roon, the playlist will be in your Roon backup. If the migration process is followed and the backup is restored, those playlists should migrate over through the backup.
Can you confirm that your play counts and history from before the migration are also present on the new Core machine?
When you switch to a new Core, you can restore a backup if you’ve made them previously, but this isn’t automatic. If you have a backup available from before the migration, you can restore that and you should see your playlists. You can read more about backups and the restoring process in our KB.
Your library looks like it has been rebuilt from your files on the new server that is why you have no playlists or history. I would contact the person who did the work and ask why they didn’t do a backup and restore.
As Ged suggested, this is most likely because your library was re-imported fresh rather than migrated properly as outlined in the migration guide linked above. You’ll want to restore a Roon backup and follow the instructions listed there to make sure that everything is properly brought over to the new Core.
