    • In one embodiment, a storage controller comprises a first port that provides an interface to a host computer, a second port that provides an interface to a storage device, a processor, and a memory module communicatively connected to the processor and comprising logic instructions stored on a computer readable storage medium which, when executed by the processor, configure the processor to copy a logical disk mapping from a first storage array managed by a source storage controller to a second storage array managed by a destination storage controller by performing operations comprising obtaining, in the source storage controller, an object identifier listing for use with the logical disk mappings in the destination storage controller, copying, in the source storage controller, contents of logical disk mappings for use in the first storage array from a first storage container to a second storage container, and replacing, in the source storage controller, object identifiers associated with the logical disk mappings in the first storage array with object identifiers from the object identifier listing received in the first storage controller.
