Hi, we are suppose upgrade our existing UCS infrastructure to the firmware version 2.2(6c), I have opened a tac case in order to get cisco expertise advice on behalf of this upgrade, we are running a highly critical system at a leading airline in sri lanka. The support engineer who handle the particular case informed me today that, it we would upgrade to the Firmware bundle 2.2(6c), we will not be able to downgrade the firmware level. Currently we are running firmware version 2.1(1a). Please advise. i could not detect when i go through hardware and software interoperability matric.
