Abstract
Embodiments of the invention relate to systematic migration of data. Data is streamed to data storage and stored in a virtual storage device (VSD). Stored data is systematically migrated from the VSD to a higher density VSD, while streaming of data is also switched to the higher density VSD. Source and target data extents are maintained and merged upon completion of the data migration, together with linking the streamed data blocks with the migrated data blocks in the order presented in the input stream.
