I don't think there is a guide. How you do this will depend on how complex your requirements are.
If you've just got a bunch of identical users, with mailboxes on the same server, and one domain, and no list server, then things are going to be quite easy.
Migrating the mailboxes might be a bit trickier: there's a guide at
http://wiki.dovecot.org/Migration/Courier
We use Cyrus IMAP with LMTP delivery, which allows Cyrus to index mail as it's delivered. Exim should be able to deliver direct to maildir mailboxes regardless of whether they're for courier or dovecot.
You might find it easier to do the Exim replacement before the IMAP server replacement. That way, if you have any problems they'll be easier to diagnose.
