Updating with DSM 7.2 Container Manager

[zen_arcade]

Hi there

I'm currently using Jellyfin server 10.9.6 on a Synology DS224+. With some tinkering, I finally got to run every transcoding gpu option right, and everything runs smooth. I don't remember exactly what I did, but I seem to remember changing something manually in a yaml file, and getting Container Manager to import it again. Anyway, it wasn't something I look forward to doing again.

Now Chromecast really wants Jellyfin to be updated, so I must do it. Now the question is: what is a bulletproof way to update my Jellyfin image in Container Manager and 1) preserve my current container, especially my hard-earnerd HW options 2) rollback everything is things go south?

My Jellyfin.json exported by Container Manager is pasted below. I don't see any of the /dev/dri options I had to tinker with, so I already sense some fuckery, as if Container Manager doesn't know they are there. I understand they might be in my local /docker/jellyfin-server/config directory, but I don't know enough to be confident about it.

Many thanks in advance for any hints
