I have two pairs of Brocade switches running FOS.
The original pair is running 7.0.1 and my new pair is running 7.2.1d.
I intend to buy a licence to interconnect the two pairs and extend the fabric onto the new switches. Can anyone advise whether the two FOS versions are compatible/interoperable or whether I would have to downgrade the new switches to 7.0.1?
Is there some documentation which confirms compatability?

Found the answer in the release notes for my switch FOS version, page 14 'Supported Products and FOS Interoperability'

I was going to downgrade the new switches to 7.0.1 to ensure compatability, but found the following document:
It transpires that the 6520 can't run a FOS version older than 7.1 so I cannot downgrade it. But also on page 12 the document states the following about legacy devices only being supported through FC routing:
12Q.Will Brocade 6520, 6510, and 6505 Switches work with existing firmware versions in current fabrics?A.Brocade 6520 Switches require Brocade FOS 7.1 or higher. Brocade 6510 Switches require Brocade FOS 7.0 or higher. Brocade6505 Switches require Brocade FOS 7.0.1 or higher. Brocade 6520, 6510, and 6505 Switches are compatible with all 8 Gbpsplatforms and 4 Gbps platforms operating with the appropriate firmware. All other legacy devices running prior versions of BrocadeFOS are supported only through Fibre Channel routing. For complete support information, please refer to the respective BrocadeFOS release notes.Does that mean I couldn't use the two switches together with an interconnect as originally intended?The release notes bear no mention of the above limitation. What limitations will this impose?Thanks,James

Thank you for your response. It's not that I am unable to find the information in the release notes. The release notes state there is compatability between the two versions. However the PDF document which I linked above states that they may only support FCR between the new and legacy switches. The PDF document does not specify what is considered to be a legacy device. The release notes make no mention of this caveat.
I am unable to update the FOS version on the older switches, so I am wondering will I be limited to FCR only support and if so what are the implications? Or should I expect both switch pairs to be able to interact via standard E ports as per normal?
