A customer is using Cisco MDS to consolidate several McDATA SAN islands. The migration plan is to cut over the storage ports to the MDS first. IVR would then be used to route between the MDS native VSAN and the individual McDATA interoperability VSANs. The remaining devices on the McDATA VSANs would then be moved to the Cisco VSAN in phases. Since there are overlapping Domain IDs across the McData VSANs, which of these must be configured?
