i can't think of any native tools, could be a scripting project.  Export VSAN zoneset to a file and then parse it with perl and turn it into something like this (brocade config file)  alias.hp_msa04_a2:21:70:00:c0:ff:da:d8:0a alias.hp_msa04_b1:24:70:00:c0:ff:da:d8:0a  zone.oracle1_hba1_hp_msa01:hp_msa01_a1;hp_msa01_b1;oracle1_hba1zone.oracle2_hba1_hp_msa07:hp_msa07_a1;hp_msa07_b1;oracle2_hba1  I am not sure if you are using DCFM to manage your Brocade but in DCFM that format is XML
what is the best way to import zoning from cisco fabric over to brocade fabric?
cisco to brocade
