Hi Chris, Thanks for your help.  What we ended up doing was:
We have a MD3220 that has a failed RAID controller.  We have acquired a replacement controller, but it has newer firmware than the existing controller. From my understanding, once the new controller is installed it should have the configuration and firmware copied over from the existing controller.  Do we need to upgrade the firmware on the existing controller first, or will the copy process downgrade the firmware? Ron
