Migrating IMAP mailboxes to a new Server

[ra3ndy]

[edit] sorry for having posted to the wrong category initially! [/edit]

I'm looking for a good solution for migrating about 45 IMAP mailboxes from a nearly-full server to a new server (both hosted remotely by Rackspace, who won't help, since they won't be liable for data loss).

Both systems utilize the PLESK interface, but the shortcoming of the PLESK Migration Manager is that it needs to create a dump file first, which our current server doesn't have the drive space for (thus why we need to migrate to a new server)

So what I'm asking is: Is there a good way to migrate these mailboxes to our new server without having to manually copy them from inside Mail?

Here's one thing I've tried: imapsync. Which is for UNIX systems. I thought I'd try to get it to run in Terminal, but no luck ('make' command not found when installing modules)

If anyone knows of an app or any process that can help me out, it'd be much appreciated. Thanks in advance.

To get imapsync installed, first install the Apple Developer Tools, which you may have on a disc that came with your computer (not the O/S install disc), or you can download it for free from http://developer.apple.com/tools/xcode/ (registration required, but it's free and quick). That includes the "make" command, compiler etc. you'd need to install imapsync.
