Looks like I did a better job deleting the old MBs before than I thought... there are none left.
It just doesn't seem like much of an "upgrade" when you pay money to go from 50+ mailboxes to 8. I mention "credit" because I would think that you would get a reduced price or some other benefit based on the number of mailboxes you had previously since you had already paid for them once.
I wasn't involved in that upgrade though, so forgive my ignorance.
