SOLVED: Migrate Jellyfin from truecharts container to truenas'

[lirayah]

So basically, since the last major update from IX for Truenas Scale (Dragonfish), Truecharts is getting discontinued because of how the apps will be handled and those won't receive any further updates.
So I need help to migrate all the stuff (like users database and watch status but also JF config files).
Could you guys help me ?
