Jellyfin 12 should be able to use a Plex media library using Plex naming conventions, no renaming required.

This will reduce the switching workload, and you can run both services at the same time whilst trying out Jellyfin.

Huh. I was able to run Plex alongside Jellyfin on my library no issues.

		Just depends on what naming conventions you use. For foolproof matching, adding Plex metadata in the style of "{tmdb-12345}" to the directory name would cause problems for Jellyfin, as they used to demand different formatting, for instance square brackets. It has taken a years to convince the maintainers that this change is a good idea and not "letting Plex determine the future course of Jellyfin."
