IBM z/OS DFSMS Cloud Data Manager (DFSMScdm) can migrate existing DFSMShsm data from ML2 (tape or virtual tape) to MLC (cloud storage) while still maintaining the data set's migrate date and date last referenced. Moving data to cloud, including object storage in the IBM TS7700 tape library, can help you reduce future MSU consumption and reduce contention for data stored on serial tape.
