Tried the migration wizzard on my Exchange 2003 mailbox. Worked fine and all mail got tranfered to Zimbra just fine, but a few folders in my Exchange mailbox appeared to be gone in Outlook afterwards. Had to create a new mapi profile to get things working again in Outlook (and lost al my extra mailboxes I added over time)

So why are things being changed in the mapi profile when doing a migration?
