[Dovecot] dsync to move from 1.2 to 2.0

I'm not certain of the correct syntax for this - and I'm reluctant to risk my live data by experimenting. I've setup a 2.0.2 server on a virtual machine, and I want to copy a live account over to it for testing. Not that it should matter, but the 1.2 machine is using maildir and I want to give sdbox a try on 2.0.2.

I'm assuming (dangerous, I know) I should run dsync on the new 2.0.2 machine, and connect remotely to the 1.2. If it matters, my usernames are complete mail addresses, i.e. myname@mydomain.com, and are stored as /var/mail/domain/name/Maildir.

Does dsync perform an imap connection to the remote server to pull the mails? Or am I confusing this with imapsync?
