I think what he provided is useful. IMO the migration utility within SM to move email is unreliable. We've tried using it many hundreds of times, it stalls, duplicates emails, doesnt seem to ever really complete, has errors etc. We simply wrote an app that uses imapsync to process emails for us when migrating just email, it works brilliantly.
