A technique for achieving data mobility between storage systems having different block sizes includes identifying a baseline size that is common to the block sizes of the storage systems. The technique further includes generating fingerprints of blocks based on extents having the common baseline size. Fingerprint-based data mobility is then achieved by comparing extent-based fingerprints, or combinations thereof, across different storage systems to identify matching data.
