Tigris is back in service.
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.
