Abstract
Described is non-disruptive data migration from a source virtual array at a source storage array to a target virtual array at a heterogeneous destination storage array. A name server database is queried to obtain port names for each source port. The source storage array is queried to obtain information about each source virtual array LUN. A target virtual array is generated at the destination array for receiving a copy of data resident at the source virtual array. The target virtual array has at least as many ports and at least as many LUNs as the source virtual array. Data resident in the source virtual array LUNs are copied to corresponding target virtual array LUNs. The name server database is reconfigured to associate source port names with the virtual port addresses of the target virtual array such that the target virtual array appears to a host as the source virtual array.
