[Dovecot] Dovecot with mbox and maildir

[Dario Ale]

Hello,
I have a question, i need migrate from old mail server to new mail 
server, the mailboxes format in the new mail server is maildir, in the 
old is mbox, the problem is that only the INBOXs are approximately  64Gb 
(are 7000 users), in the new I installed Dovecot, in the old is UW-Imap.
The question is, Is there any form for have mbox and maildir 
simultaneously with Dovecot?
I am using Postfix, my MDA is procmail, this write mailbox in the 
correct format, then i can copy all INBOXs and HOMEs to the new mail 
server, and change the mailbox format "slowly", supposedly procmail 
detecting the mailbox format and Dovecot could detect too.

Thanks, very much.

pd: sorry, my english not is good.
