The upgrade attempt had to be abandoned, however, and we’re still running the same version we were before the attempt.

The upgrade ran into some mysterious problems during database conversion. I say “mysterious,” because the upgrade had already been verified once, off-line. We don’t, at this point, know why those tests passed yet the actual upgrade failed, but we’re digging into that very hard.

When we’ve understood that, we’ll be doing another off-line trial run, and possibly some data clean-up, before another attempt. Details will appear here.
