I am using Brocade 300E (IBM branded 2498-B24), version 6.1.0c and second one is 6.4.0c both switches are interconnected.
I want to upgrade both switchs FOS to 7.1.2b release. Please guide me to get the upgrade path.
6.1 > 6.2 > 6.3 > 6.4 > 7.0 > 7.1
I would suggest to follow Brocade official procedure, see URL below.
