Well, I uploaded, set permissions, ran cgi thingies, and I think I've got it all installed. My sign-in says 3.11 though my weblog is still saying 2.64. Also, my login entire menu is justifying on the left, which better not be correct because it's really annoying...
Going to bed now, wish me luck.
OK, I actually broke down and paid for a license to MT 3.11 and I think I've backed up everything that can be backed up, so I'm going to give it a shot. Just FYI, in case anything acts weird this weekend...
