A.
correlation of semantic characteristics of the data migrated between the two systems.

B.
correlation of arithmetic characteristics of the data migrated between the two systems.

semantic characteristics. A review of the correlation of the functional characteristics or a review of
the relative efficiencies of the processes between the two systems is not relevant to a data migration
review.
