TrueNAS will be moving away from Kubernetes/Helm charts to Docker/Docker compose in Electric Eel TrueNAS Scale builds and on. You might want to reconsider this move unless you are gonna stay on an old build of TrueNAS. Not sure what is going on with TrueNAS Core. There are other NAS OS options too.

My experience with migrating data varies dependent on the app. I don’t have experience with Navidrome so I can’t really help there. Using in-app tools to migrate to a new implementation usually has the best results when working with networked data with metadata in a DB.
My parents showed me the episodes of TNG that didn’t have any content they objected to and taught a moral lesson. Most episodes have a moral lesson so I got to watch most of TNG before I was an adult. I have since then watched most of the available Star Trek content out there outside of anything TOS. I may find it in me to watch TOS but I’ve been hesitant to go back before TNG because that show is special to me.
