Well, in summary, I completed the move on Friday night. Everything went as planned.
Frankly, I was surprised at the speed of the DNS updates. Within a few minutes, my home bind instance was cranking out the updated info. I still went through the motions and updated the "old" machine to access the new database (and included a warning on the board that any attachments weren't going to carry over if you uploaded to the "old" machine after the cutover to the new machine - I wasn't in the mood to setup rsync just for that.)
The only issue I had (have actually) is that mail alerts suddenly aren't working - and they were prior to the refresh of the db and the uploads directory. I'll have to start a new thread on that one...
Anyway, thanks for the help. Mission accomplished.
