Move Mail/WebServer from G4 to G5

[jxself]

I am in a similar situation. I’ve set up a new machine running OS X Server. It’s up & running and everything seems fine.

How do I move everyone’s mail over from the old server? I can’t simply replace their new mailboxes, because the new server is already up and running and they’re already receiving mail & what not.

I found the mail sitting in /var/spool/imap/user/xxx. I had considered feeding the messages to the Cyrus deliver program, but I’m not sure of the syntax to use for it, etc. or if that’s even the best way.

All of their past IMAP mailboxes, etc. would need to be re-created as well (including the messages inside them.)

I don’t mind the messages getting marked as new again or being downloaded again or whatever. I just want to get them back.

I’d also considered using Fetchmail but the old server won’t boot (but I can access all of the files, etc. on the drive.)
