Yea I changed over to v3 without issue recently too, I read the release notes and some of the issue conversations on github, so I knew what to expect.
That’s something a lot of people dont do, if you are self hosting an open source project it’s on you to stay on top of those things, stay updated as much as possible but dont do major jumps blindly without backups.
In my case, I went from a regular immich in a container to one with openVino built in for gpu accelerated image analysis and face detection, and I had to change my database container image. Then it fired straight up and everything seems to work 100% so far.



immich hasnt had any major breaking changes for a while in my experience using it for a few years, anything that does break is probably some third party integration or plugin that would have to wait for it’s own maintainer to fix, that’s pretty normal in the open source world.
