Abstract

A method, non-transitory computer readable medium, and computing device that receives metadata for a block associated with an object from a source storage node. The metadata comprises a source object identifier and the object is associated with a source volume of a source aggregate owned by the source storage node. A determination is made when another block associated with the object has been previously received. A destination object identifier is obtained based on the source object identifier, when the determining indicates that the other block associated with the object has been previously received. A new aggregate block number is assigned to the block based on the destination object identifier and another portion of the metadata. Ownership of the source volume is transferred upon receipt of an indication of a cutover from the source storage node in order to migrate the source volume to a destination volume of a destination aggregate.
