Abstract
Embodiments include methods, apparatus, and systems for data transfer in storage systems. One embodiment includes a method that transmits a state of cached write data and mapping metadata associated with a disk group from a first array to a second array and then transfers access to the disk group from the first array to the second array while host applications continue to access data in the disk group.
