FabOS upgrade

 

Dear Brocade Community:

 

I have 2 EMC branded Brocade 6520 fiber channel switches that are running FabOS 7.2.0.d.   EMC is recommending to upgrade them to FabOS 7.3.1.C or 7.3.1.D to remedy what EMC calls the I2C bus defect in the switch firmware.   

 

I also have 4 IBM branded 5470 Brocade switches that are mounted in IBM blade centers.   Two of the switches run FabOS 6.3.1b firmware and two run FabOS 6.4.2b4 firmware.  

 

Will the 5470's  switches at their current versions of firmware continue to interoperate with Brocade 6520's after the firmware upgrade to FabOS 7.3.1.C or 7.3.1.D ?

 

Also, if I want to upgrade the IBM 5470's to 7.3.1C/D can I go directly from their current versions or do I have to upgrade to FabOS 7.0 first and then to 7.3.1.  

 

Thanks,

 

Ed Sowinski
