1. A method to perform file system migration, the method comprising:
- associating a source block device to a destination block device, wherein the source block device and the destination block device include a plurality of source blocks and destination blocks, respectively;
directing at least one command for a source block from the plurality of source blocks to the source block device or the destination block device based at least on the associating; and
updating a destination block from the plurality of destination blocks based, in part, on the at least one directed command.

Abstract
A method to perform file system migration is described. The method comprises associating a source block device to a destination block device, wherein the source block device and the destination block device include a plurality of source blocks and destination blocks, respectively. At least one command for a source block from the plurality of source blocks is directed to the source block device or the destination block device based at least on the associating. Further, a destination block from the plurality of destination blocks is updated based, in part, on the at least one directed command.

6. A computing device comprising:
-
a processor; a memory coupled to the processor, wherein the memory comprises; an association module configured to associate a source block device with a destination block device; and a migration module configured to, determine whether at least one block on the destination block device, associated with at least one block on the source block device, is updated on the destination block device; and migrate a file system on the source block device to the destination block device based on the determination. - View Dependent Claims (7, 8, 9, 10)

11. A computer-readable medium having a set of computer readable instructions that, when executed, perform acts comprising:
-
in response to at least one command for relocation of at least one block on the source block device, relocating the block from a source block device to a destination block device based on an association between the source block device and the destination block device; and updating a file system update bitmap associated with the source block device in response to the relocating; copying at least one other block from the source block device to the destination block device based on the updating, wherein the other block has not been relocated. - View Dependent Claims (12, 13, 14, 15)
