Patent ID: 8326798

Claim:
A method comprising: migrating data from a source volume having a source file system type on a first storage system to a destination volume having a destination file system type on a second storage system, wherein the source file system type is different from the destination file system type, and wherein the source volume comprises an object, identified by an identifier, configured to be accessed by a client device; generating, by the first storage system, difference information from a source file system on the source volume; generating, by the first storage system, a file system agnostic representation of the object in the source volume from the difference information, wherein the representation comprises the identifier and file data; transmitting, by the first storage system, the representation to the destination volume having the destination file system type; and converting, by the second storage system, the representation to conform to the destination file system type, wherein the converted representation always comprises the same identifier and the same file data from the source file system.
