The machine with the mail spool completed the upgrade up to the point of reboot, but it doesn’t appear to be coming back up so I may have to go to the co-lo and physically boot it. It might be stuck in the boot process, may not have shut down completely, hard to say at this time.
The machine with the home directories got stuck at a point in the upgrade process and I may be forced to interrupt it and finish by hand (which is a painful process).
