Abstract
Non-disruptive data migration from a source array to a destination array entails generating a virtual array spanning at least one destination array for receiving a copy of all data at the source array. The virtual array has at least as many virtual ports as physical source ports of the source array and at least as many logical units (LUNs) as the source array. Each source array LUN corresponds to a virtual array LUN and equals the storage capacity of that corresponding LUN. Each virtual port has a virtual port address. All data resident in the LUNs of the source array are copied to corresponding LUNs in the virtual array. A name server database is reconfigured to associate port names of the physical source ports with the virtual port addresses of the virtual ports such that the virtual array appears to a host as the source array.
