It is a small program that makes IMAP connections to the source and destination servers and copies all messages/folders and message attributes across. It's biggest advantage is that you don't ever need to touch the backend mail storage since each IMAP server itself is interfacing with the raw mail files (meaning it will write the files the way it likes them). It's biggest disadvantage is that you need to know the username/password for each user you are moving but it's a question of choosing your poison I guess.
