dovecot - Mar 2012 - Is it possible to migrating mail to dovecot using imapc?

I'm excited to hear that dovecot now supports imap as a mailbox type.

I've got a mailbox over on another imap server, which I want to migrate to
dovecot. 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, I can't find much documentation on imapc, other than it exists.

Is this kind of move possible now? Would someone mind giving me some hints as to
how to make it work please?

Thanks :),
Joe

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.
