User case: Samsung Data Migration to smaller SSD

“On a friend's computer, I need to migrate applicationsdata from a 1TB HDD to a 500GB SSD. Does the Samsung data migration tool allow me to migrate data from a larger HDD to a smaller SSD if the source usage data fits the capacity of the smaller volume? The laptop hasn't arrived yet and the SSD hasn't been purchased yet. If a larger 1TB capacity SSD is eventually necessary, then other laptop upgrades will have to be eliminated to balance the upgrade budget.”
