I was wondering whether I could use 'doveadm backup' to setup a two way synchronisation process between the old imap mailbox and the new dovecot mailbox. That way I can do the migration, and can coordinate the mail clients changing where they pick up their email from later.

One-way sync will work fine. Two-way sync might be a bit troublesome. For redesigned dsync I've started thinking about kind of a 1,5-way sync. :) That would make sure that all messages from A are copied to B and no messages are deleted from B, but doesn't try to copy new messages from B to A.

http://wiki2.dovecot.org/Migration/Dsync anyway has some docs.
