We are in the process of moving our Windows SAN to Brocade connected Hitachi SAN. The new setup includes 2 Brocade 4100 and a Hitachi AMS500 storage. The old setup aka current production SAN includes 2 SUN vixel hubs connected to EMC SAN and they are fiber channel copper cables (HSSDC connector). Is it necessary to have a physical connection between Vixel hub and Silkworm 4100 for data migration? If so, how could I accomplish this?
