I believe I posted this here a while ago, but only one of the scripts was working at the time. I finally circled back around and got the others working as well.

- Migrate all Plex users to a Jellyfin server (using the same usernames and randomly-generated passwords)

- Migrate all playlists from Plex to Jellyfin (this only migrates the playlists that the Plex admin user can see. Support for all playlists coming soon (for the time being, though, seems any user on Jellyfin can see any playlist: https://github.com/jellyfin/jellyfin/issues/2410))

- Migrate user ratings from Plex to Jellyfin (any movie or music track that is 6.0 or above on Plex is "liked" on Jellyfin).

- Mirror Jellyfin users from one Jellyfin server to another

Always down to create more scripts if you can think of other things that need to be transferred from Plex to Jellyfin!
