Migrate Server Mail IMAP to other server

Our Mac (Lion) Server is currently having issues and I'd like to wipe fresh and start again. We currently have IMAP with around 40 mailboxes set up on the server, and I'm wondering how to port the mail accounts and mailbox contents over to the fresh server with the least administrative effort.


Any ideas?

if your users and import them into the new server, them all users will retain their GUID.


All mailboxes are named with the user's GUID.


On new server, import users. Setup mail service from scratch.

Copy the GUID mailboxes from old server to new.

Reset permissions of the mailboxes.


Its pretty straightforward.


The key is to keep the same User/GUID list.
