I just upgrade my box from 42.3 to 15. Just one heart-stopping period.
I used zypper dup and the good news is that it performed the upgrade apparently successfully and didn't complain about my reiserfs filesystems, which still work.
Yes, I'm also considering to use zypper dup for my systems with reiserfs :-( Also encrypted partitions make the DVD upgrade to crash.
The heart-stopping moment came when I rebooted. I saw the h/w start up, and then grub, and the opensuse stuff* and then it switched to X (or at least an X-style arrow mouse pointer appeared. But it then just sat there with a black screen. Initially it didn't seem I could do anything at all, but after rebooting again with nomodeset I was able to select text-mode tty2. After a lot of faffing around and getting frustrated I started yast in text mode and went to update-alternatives and switched from sddm to lightdm. After I rebooted, everything worked.
I have no idea why sddm wasn't working, but then I have no idea why it chose sddm when I was previously using lightdm.
Because the setting in "/etc/sysconfig/displaymanager" is deprecated and ignored. It is probably a bug that update-alternatives was not initalized with the previous default instead of creating a new one, but not something that can be solved at this point, too late.
* I also have no idea why the stuff I saw at bootup included plymouth, since it wasn't installed before the upgrade. I've deleted and tabooed it.
Yes, you have to taboo things you really do not want, or they may come back to you.
One thing that wasted my time was that during the upgrade I was asked to approve a licence - something about nvidia video. Now my box doesn't have an nvidia hardware; it uses Intel 915 video. So one of the things I tried to fix my problem was to remove some packages with nvidia in their name, on the offchance it was a driver issue. But I couldn't remove them because of lots of dependencies. What's going on there? Why do I need a whole bunch of packages with nvidia in their names even with no nvidia hardware? And why do I have to agree some special licence?
Paste the output of "rpm -qa | grep -i nvidia". And also "hwinfo --gfxcard" to make sure about your video hardware. It is possible that you have installed some video coding software that make use of the GPU, and thus the driver is installed even if you don't have the hardware.
I wonder what other gotchas await? Hopefully none.
Probably more :-p -- Cheers / Saludos, Carlos E. R. (from 42.3 x86_64 "Malachite" at Telcontar)
