Hello. Zypper can add iso files as repo. Can I simply go for a zypper dup (zypper in zypper maybe first?) via the downloaded .iso image file of 12.1(x86) on my running old 11.2 system? Or is it better to boot via 12.1 media and taking the system offline? Or is zypper able to handle all those changes just fine by now via dup? Thanks.
Zypper dup procedure is only supported for one version jump.
It's only *tested* for one version jump is more correct.
I've done the 11.2 -> 11.4 upgrade. No problems I did not cause myself (having locked packages and broken dependencies ;) Before that I did a 11.1/32bit -> 11.2/64bit upgrade with zypper.
As to whether the method you propose via iso image works, I do not know.
I have the ISO as a repo and also did the upgrade with that. I did (and will do in the future) this: copy the system to a second partition with rsync. I.e. I made a second system-partition, and ran rsync -auxlPRAXSHD --delete / /NEW_ROOT and then added the copy to grubs menu.lst, and as I kept working during the rsync ran that rsync again directly before booting the copy (which also updated the menu.lst[1]). Then, having booted the copy I - changed repos from 11.2 to 11.4 - checked that repo-priorities are correct, e.g: packman < update < iso < oss/non-oss main repo - zypper clean - zypper ref - zypper dup and resolve any conflicts which in my case were fewer than I feared, as I break quite a few packages ... Talking of that, I'm just re-syncing back the upgraded system to the (cleaned) partition the 11.2 was on, in order to run the upgrade to 12.1 with that. [1] if I wanted to remove the original and keep the copied and upgraded system it suffices to just reinstall grub from that system.
The pre-11.4 zyppers had a bit of a problem with package ordering, so you might run into trouble with a direct 'zypper dup'. It *should* work if you lock the "liblzma0" package (zypper al liblzma0) before doing the 'zypper dup'.
Haven't noticed that when I did the upgrade, never booted the old system since booting the copy to run the upgrade ;)
I'd recommend to boot the iso so that the 12.1 software stack is used, just to be on the safe side. But, as I said above, a 11.2->12.1 update is untested, so there may be some other issues you might run into.
Yeah, 11.2 -> 12.1 is a bit steep, esp. as the change to systemd may
cause additional trouble. Well, doing the upgrade on a copy keeps the
mind quite relaxed, just reformat the copy, and start fresh with
rsyncing ;)
