  Yes you can do it, provided that you have a version 7 system to perform the flash downgrade. You will get a warning from the controller upgrade utility on the v 7 system, but you can still do it. When a controller comes out of the factory, it comes with the latest firmware. Frequently, end users are on an earlier version and must flash downgrade to match their production system, so you are in good company.
