What happens with the "White spaces" during initial migration with SME?
Given a disk with approx 500 GB size and 400 GB occupied by Exchange databases. A check with Get-MailboxDatabase -Status tells that there is approx 50% "White Space" amount due to an archive operation with a 3rd party tool.
Will the LUN after a migration with SME (from local harddisk to FC attached LUN) only consume approx 200 GB?

No. It simply copies the Exchange database as is. In order to remove your free space you would need to make a new mailbox database and then use move mailbox cmdlets to remove the white space.
Note that the white space does not impact NetApp SnapManager backup times as a traditional tape backup would.
