using Murder for migration from UW IMAP

[John Alton Tamplin]

Would it be possible to use Murder to migrate from UW IMAP? I have Cyrus setup and running on a new machine, but the problem is that taking everything down and converting all the mailboxes would be too much downtime (2-3 days). What I was thinking of is setting up a frontend server with UW IMAP and Cyrus as the backend servers, with the initial mupdated database showing all the mailboxes were on the old IMAP server. UW IMAP isn't going to talk to mupdated, but if no mailboxes are being created there it seems like that won't matter. As each mailbox is moved to the new server, the master list of mailboxes is reflected to update the new location.

From my inspection of the documentation and some of the code, it looks like this should work with a couple of caveats (during the transition, users have to be prevented from creating new mailboxes -- this can be hacked in the code, and connections that have been referred to the old server have to be broken when the mailbox is transferred). Does anyone see a reason why this won't work or any other gotchas to watch for? Thanks.
