Hi Scott,
I do not have any experience with SurgeMail.
Recently I used imapsync
(http://www.freshports.org/mail/imapsync/) to migrate about
250 mailboxes from courier imap to dovecot. I wrote a little
perl skript to fetch the login credentials from MySQL and then
sync each mailbox.
Can´t say much about performance or scalability, but I have
read of people migrating/syncing about 20k+ mailboxes with it.

We used dovecots PostLoginScripting with
courier-dovecot-migrate.pl to convert the Mailboxes at the first
login time. See http://wiki.dovecot.org/Migration/Courier.
170'000 mailboxes were migrated from courrier to dovecot this
way.

For other Systems have a look at
http://wiki.dovecot.org/Migration

Have fun,

Michael
