I now have a Brocade 2800 (version 2.6.0f) that I would actually like to back rev to 2.1.9d. First, is it possible to flash an older version of the firmware and have it work? Second, I need the binary of 2.1.9d (or any other 2.1.9x version) to flash. Anyone know of a source on the web (or could email it to me), seems that the oldest version on the Brocade site is 2.6.2? I also have a 2.1.9d machine, is it possible to suck it out of the machine somehow?
