Zusammenfassung:A method, computer program product, and computer system for full allocation volume to deduplication volume migration in a storage system. The method includes moving a physical allocation of stored data associated with a full allocation volume into a virtual address range in a deduplication domain and setting up the deduplication metadata to be a passthrough. The method then performs a background deduplication process on the virtual address range once populated with the physical allocations using a drive query hash interface to perform hash calculations on physical drives at which the data is stored.
