Is it possible to move Jellyfin from centos to ubuntu?

[TheDreadPirate]

Follow this process to migrate to the new Ubuntu server.

Backup/migrate these folders on the CentOS host.

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

Install Jellyfin 10.10.3 on the new Ubuntu host. Once the install completes, stop the Jellyfin service.

Restore the folders I mentioned above. Then ensure jellyfin owns the folders.

sudo chown -R jellyfin: /etc/jellyfin /var/lib/jellyfin /var/cache/jellyfin

Start the Jellyfin service. It will likely take several minutes to start since it has to apply A LOT of database migrations going from 10.8.10 to 10.10.3. Be patient, do not interrupt it.
