Moving from Plex to Jellyfin

[Mel_Gibson_Real]

Which is weird because it works fine for every single of the 5,100+ films I added, but not for the TV shows.  Is there a reason you could think of to explain that?  Also, I figured there were some changes required as I mentioned in my post, so my question was more about finding an automated, or more automated way than renaming each file one at a time.  There are more than 20k files to change.

I would use sonarr. You should be able to change the file structure to jellyfins perfered layout on mass. Ive done it once or twice and had minimal issues.
