IHAC that requires a fabric migration from their existing all brocade fabric to a new Cisco core. There are various blade centers that have brocade modules in them in fabric mode. To attach to new Cisco core director all of those modules will have to be converted to access gateway mode. I'm looking for someone that has performed this type of conversion in the past that can lend some direction and experience on the best way to accomplish this will the least amount of disruption as possible. Please reach out indenpendently if you'd like to see details of the environment as i'd have to scrub them prior and it's best shared over email. Thanks.
