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.

But, 'dsync mirror' does a two way sync, doesn't it? Can't I just do that with imapc as the source mailbox?
