The problem comes with IMAP. While dovecot can tell if a folder is mbox or maildir, it has to be pointed to the right place (by namespace definitions in the client, IIRC), and the default of putting the inbox under ~/mail is one I'd like to embrace for various reason...but given that that means moved inbox folders and *that* means either making a global change (there goes staged migration) OR changing the namespace definitions on each PC. I can get to the early few and change the namespaces definition, but there doesn't appear to any equivalent (enlighten me, if I'm missing something) to ~/.procmailrc for imap, so that I don't have to get on the client machine.
By namespace definitions you probably mean the IMAP clients' "imap folder prefix" or whatever they happen to call them in different clients? You can create namespaces for backwards compatibility, you probably want similar namespaces to what is described here under UW- IMAP examples: http://wiki.dovecot.org/Namespaces
You could do that kind of a change already with mbox users to make sure everything works. Then have your users use one of the two mail_locations (by returning "mail" extra field from userdb):
* mail_location = mbox:~/mail * mail_location = maildir:~/Maildir
