SOLVED: Updating Server on Ubuntu 24.10

You wouldn't be able to drag and drop your current install's files into Docker, but it is possible to use your existing files with a little work.

You'd need to back up the following directories before trying, just to be safe.

/var/lib/jellyfin
/var/cache/jellyfin
/var/log/jellyfin
/etc/jellyfin

Our documentation contains the parameters you need to add to your docker config to make use of your existing files.

Essentially, a default Docker instance of Jellyfin writes everything to the virtual paths /config and /cache. Adding the environment variables specified in the documentation overrides the default Docker behavior.
