I might dupe over the partition and try the upgrade on that. I'd love it if I could always have the happy fallback :-)
That's the most common method used here over the years. Multiboot is in my blood since decades ago. But with 15.3, I've done nearly as many fresh installs as I've done 15.2 to 15.3 online upgrades of cloned partitions. IIRC I did do one or two offline upgrades lately, but I think it was only (very long since last updates) TW to TW rather than any 15.2 to 15.3. If you're going to try an online /or/ offline upgrade, I highly recommend considering to first disable all optional repos, then zypper dup 15.2, then dup to 15.3, then re-enable any disabled repos you still require. In particular this applies if using NVidia's proprietary graphics drivers. Packman might not be any problem, as long as you aren't upgrading while its mirrors are in a transitional state. -- Evolution as taught in public schools is, like religion, based on faith, not based on science.
