Abstract
Enabling an off-host computer to migrate data of a data volume. In one embodiment, the off-host computer copies data contents of n data blocks of a first data volume to n data blocks, respectively, of a second data volume. A host computer is capable of modifying data contents of a first plurality of data blocks of the n data blocks of the first data volume after the off-host computer begins copying data contents of the n data blocks of the first data volume to the n data blocks, respectively, of the second data volume.
