An embodiment of the invention provides a method for migrating data from one location to another comprising establishing a new memory location under control of a specific memory accessing device. The new memory location being where data, which is being migrated from a first memory location, is to be resident, the specific accessing device taking control of a certain portion of data resident at the first memory location, the control preventing the certain data from being accessed by any device other than the specific accessing device, obtaining, under control of the specific accessing device, a most recent version of the certain data from the first memory location, forwarding the obtained certain data to the new memory location, and when the obtained certain data is forwarded to the new memory location, marking the certain data as being gone from the first memory location such that attempts to access the certain data at the first memory location from a specific accessing device will be redirected back to the accessing device for redirection to the new memory location.
