I’m considering upgrading my openhabian instance on rpi 4 (OH 3.3.0.M5) from buster to bullseye and I understand the preferred (read supported) method is to reinstall openhabian with bullseye from scratch. That being said, what is the least intrusive method that works? upgrade in place using apt …

Reinstall openHABian with bullseye from scratch will be the lest intrusive method that is guaranteed to work. [image] pleedell: upgrade in place using apt dist-upgrade? What is the experience with this approach? It’s more involved than that. You’ll need to manually edit the apt sources files…

Thx, that helps. I’ve updated a couple of my other rpi’s to bullseye already so I’m not too worried about the mechanics of it. I do like the cleanliness of going with a fresh install, does restoring from openhab-cli backup re-install add-ons/bindings as well?

[image] pleedell: I do like the cleanliness of going with a fresh install, does restoring from openhab-cli backup re-install add-ons/bindings as well? Yes. If you do a full backup it’ll even back up the installed add-ons. A normal backup will cause OH to redownload and install the add-ons upo…

[image] rlkoshak: Just make sure the new version of OH is the same as the old version. It usually doesn’t work to install a backup from an older version of OH to a newer version of OH. So this approach is the recommended approach. I have a question about this. When I try to install from Buste…

Wouldn’t it be a good idea for the upgrade process to do an OS check for bullseye before even allowing the OH4 upgrade to proceed on a buster implementation?

[image] jackmule: Oh it would be really great if this article or reference could be included here what do you mean by “here” ? I just did, didn’t I. And all that information is also part of the official docs. [image] pleedell: Wouldn’t it be a good idea for the upgrade process to do an …
