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