This is as I expected. It would also be interesting how long one can go between Tumbleweed updates. I ask this because we have measurement systems that are on the road most of the year. They start life with an openSUSE that we create with KIWI that has just what we want so the systems are the same. We want to keep them running releases that are still supported. Currently we reinstall the systems every year or so (when there is an openSUSE release that seems like it addresses our needs). This happens in the off season. Getting each system set up again is always a bit of work. Also, we would like non-Linux-expert customers in other countries to be able to do this with their systems. So we are looking at our options.

I have been looking at the Tumbleweed installation docs and don't see any reference to which openSUSE releases are ok to upgrade to Tumbleweed. Perhaps most recent releases are okay? But how about 12.1 or 12.3?
It should be documented, and I think it was, that the intention is to upgrade from the latest.
From experience and what I have read on the lists, upgrading is only *advised* for one release to the next, so going on that you would need to step thru the releases. *But* several have had success jumping two releases. Upgrading from 12.3 might work, key being backup-backup-backup.
You can jump some releases when using the offline upgrade method (boot dvd, choose upgrade). Obviously you can not do this for tumbleweed.
Jumping releases with an online upgrade (zypper dup) is certainly unsupported. But some have done it. I would not try.
One problem is that the rpm and zypper toolchains (including databases) may be different on the target release. When this happens, typically those tools get an online update before the next openSUSE release is published, so that both tool sets are compatible, and zypper can handle installing packages from the next release without crashing.
The trick, when jumping releases, seems to be to upgrade zypper and rpm toolchains before running the zypper dup.
But there could be other "catastrophic" changes between releases that are not catered for when jumping. You have to be careful, read mail lists reports, release notes, etc.
My advise: When in doubt if you can do it, don't :-)
Personally, I believe that soon there will only be two releases, Evergreen and Tumbleweed.
Not possible. Evergreen needs an stable released version as base.
