No. Other than: a) the griping fear of me personally (1 person) migrating 4000 users and b) the recurrent experience of trying to marshal everything necessary to do it, getting about a tenth of the way into *beginning* it and having some 4-alarm fire interrupt things...and then it's a month or two before things calm down again that I might take a shot at it again. These days, I've gotten cynical. I enjoy the peace and quiet for 4 hours to 3 days on the outside whereupon something else falls in the cart that I have deal with. Plus I have to wonder what the realities of moving from 1) mbox with one monster file to 2) maildir with inodes beyond measure and its effect on backup. Yes I know I should be able to just convert one user and find out...but the time isn't there for even that... Fear and Loathing, Sickness unto Death....... Remember: when you (the sysadmin) do things really, really right, nobody knows you've done anything. Sounds like a 0 to negative sum game......

Any particular reason you're tied to mbox other than having migrated from UW-IMAP? I suspect maildir, though not as lock-free as advertised, would have a much better time of things. (i.e. it's far better suited for multiple-client access.)
