Abstract
Described are a system and method of migrating data stored in logical units of storage (LUNs) at a plurality of source storage arrays into one destination storage array transparently with respect to a host in communication with the source storage arrays through a switch. First and second source storage arrays and a destination storage array are each partitioned into a plurality of source virtual arrays. The destination virtual arrays include a first destination virtual array and a second destination virtual array. Data stored in a LUN of a first source virtual array of the first source storage array are copied to a corresponding LUN of the first destination virtual array of the destination storage array, and data stored in a LUN of a second source virtual array of the second source storage array are copied to a corresponding LUN of the second destination virtual array of the destination storage array.
