ISL between Cisco MDS 9509 and Brocade 8510

Hi Team,

IHAC who is planning to migrate from the existing CISCO MDS 9509 SAN switches to New Brocade 8510 switches....for the migration purpose what is the best method...how can we ISL the 2 switches, transfer the zoning info and then migrate the cables?

Is there any documented procedure for this?
