Jellyfin update

[elephantLYFE]

Sorry, not sure about QNAP, but I'll share similar experience on Synology Docker setup.

I have docker(Synology) and have learned from my own mistake when upgrading Jellyfin.
I did the "reset" update container i think, and it reset and did a clean install.

Problem was i left two directories in the default docker directory (config & cache) those were deleted with clean new ones.
So i lost a bunch of my data for viewing activity, and all of the pictures for actors.
Lost my collections i had curated.
(Annoying as some i spent a lot of time manually curating certain actors.)

However, my movies/shows/music were all fine. Artwork was all ok. NFO files were all ok.
This is because i followed correct procedure for creating separate directories.


Step of creating separate folders for cache/config is mentioned in below documentation, and 3rd party blog.

Synology Specific: https://jellyfin.org/docs/general/installation/synology

Please double check your homework & research.
Above is only my personal experience.
