ratings won’t work, as jellyfin uses the spotify model of likes.

Im general it’s a good idea for the future to keep metadata in the files themselves, so they are agnostic from media managers.

I don’t know about the ratings. I just imported the music and went. What I found is making playlist public across users sucked so I used Strawberry to make the playlists and had Jellyfin discover those playlists too. I tried Navidome but it was not great either. When it comes to self hosting music it is painful. Everyone focuses on Movies and TV.

Anyway, after some work I am happy with Jellyfin.

Here is a script written for subsonic (navidrome) that a helpful redditor pointed me to a while back. Maybe Navidrome could be an alternative to jellyfin if ratings are important? I have not tested this myself as I have not put any effort into moving away from Plex as I had planned.

My best guess would be plex stores all that data (stars etc) in its database, so it would take some code/scripting to extract that data and rematch it else where for JellyFin to use. Probably not an easy feat.

I ported the ratings over with a quick C# script I wrote. It takes in the XML that Plex returns when querying your favorites and then favorites them in Jellyfin if it can find them by name.

If there’s any interest in this script just let me know. I wrote this a long time ago when I switched to Jellyfin so no idea if it still works.

Oof… I’ve had a quick google search. But I am afraid, there is no “easy” to write that stuff to the actual metadata of the file.

If I recall correctly, Plex stores all it’s data in a local SQLite database. So theoretically, you could query that database and then use some other tools to write those ratings to the database. So if you can code, you could probably whip something up in your preferred coding language and write that to the files.
