Abstract
Methods and apparatus for migrating data with minimal disruption in a storage virtualization system. In one embodiment, a method includes collecting information on a backend logical unit (LUN) having a direct path from a host, presenting the backend LUN to the host through a virtual target via the storage virtualization application, disconnecting the direct path from the host to the backend LUN so that the backend LUN is accessed by the host via the storage virtualization application transparently to the host, and migrating data from the backend LUN to a destination storage transparently to the host.
