Different problem, but please also note the fantastic "proxy" feature in
dovecot. With a bit of config this allows you to point all your users at
the new server, whilst proxying them back to the old server if that's
where their mailbox still remains.

This dramatically reduces the challenge of migrating a ton of data in a
big bang - you can migrate mailbox by mailbox and update the proxy
settings for each user as you go.

Good luck
