i must warn you....when i first did pst export from scalix to exchange and it all looked like it imported/exported fine. no errors. i found though, later, that i had missing mail randomly throughout multiple users folders. And then, to make matters worse, i tried to import again and even though i said don't import duplicates it created duplicates. End result was drag/drop via imap for folders (exchange account with imap scalix) and pst export/import only for calendar,contacts,notes. That took longer, but is 99.5% perfect.
you may find imapsync more compatible, but i still prefer the drag/drop method for accuracy in migration. Good luck.
