My current e-mail server has both SMTP and IMAP running on the same machine. I'm building a new IMAP server on a different machine that will ultimately have ten times the capacity. I'm looking for a way to migrate mailboxes from the old server to the new one without shutting down the whole service for an extended period of time. Can I use the old server as both a front end and one of the back ends for a murder configuration, with the new server as the second back end? Will that allow me to migrate mailboxes at my convenience? How do I prevent a port conflict between the IMAP server and the proxy on the old server?
You'll have to run the frontend + mupdate master on a separate machine.
Do I have to run the same Cyrus version on both machines? Currently, the old server runs cyrus-imapd-2.1.14 and the new one runs cyrus-imapd-2.3.6.
No, assuming that 2.1.x has support for the XFER/DUMP commands (I don't recall).
