I just moved from v2 immich to v3.
Literally changed the version in my env file and then deleted all docker images.
I then pulled all images and brought all containers online.
0 issues.
Immich has been running really well for us on my n100 for 10 months now. I did dual Google photos and immich for a 3 months and then exported out from gphotos.
I started 2026 with immich only. Been rock solid the entire time.
Of course that's all anecdotal and ymmv. But immich is fantastic
