I had the same multi-hour zypper dup 42.3 -> 15.0 upgrade, fortunately at a
test system, and I had made a backup. I made that test system 42.3 -> 15.0
updrade once again, but this time first I rebooted 42.3 at rescue mode, then
rcnetwork start, zypper up, sed -i 's/42.3/15.0/g' /etc/zypp/repos.d/*, zypper
ref, zypper dup. No problems this time. I'm sure the upgrade after booting from
a 15.0 opensuse dvd would not cause any problems either.
