I have a setup which runs three Brocade 3800 switches in one fabric but all are with 3.1.1b Fabric OS. I believe this is the minimum fabric os level for this hardware and hence i would like to know what is the recommended brocade fabric OS for this hardware so that i can upgrade. When i upgrade one switch at a time will the other switches get segmented due to difference in Fab OS Version. If so what is the worst case that this fabric would segment / time out when the FOS levels are different across switches in the fabric. I also read that Brocade supports upgrading upto two major/feature releases and hence how should i carry out this upgrade activity? Can some one suggest on this.
