Officially you would upgrade from 12.1 to 12.2, then 12.2 to 12.3
That is certainly the most tested approach, but several people have also reported success going straight from 12.1 to 12.3
I've never seen that official recommendation to single-step each upgrade. (Not saying such isn't recommended in some obscure place, juta that its pointless.
I've gone directly from 11.4 to 12.3 with an inplace upgrade with zero problems.
You got lucky :) (but I agree it normally works from what I see people post)
After a rpm is installed there is a %postin (post install) section of logic that gets run.
If there is a config file or on-disk structure change that has to be addressed during an upgrade, that's where it is done.
The devs can add as much backwards compatibility to that as they like, but it is only required that a smooth upgrade from the previous version is supported.

Don't think its luck at all, since I've been doing this (skipping two or three releases) since the late Pleistocene, and never had a problem. Almost everyone else says it works well, by your own admission, so I doubt I had any special or unusual luck. Perhaps a few people have especially bad luck. So either the devs are very good at taking care of this, or the so called "on disk structure change" is a relativly rare thing indeed. Worst case is some package falls back to installation default and you have to go and copy over your config files or something. Some releases ago I had one bit of Samba take a disliking to my configuration but it substituted it's own, which was fail-safe. That is just about the only thing I can recall. The only reason I switched from 11.4 is because it hit end of life and no more security patches would be forthcoming. -- _____________________________________ ---This space for rent--- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
