We are on 4.2.1 and I need to upgrade to support exchange 2010. All devices are in a group to control config other than time. Can I upgrade only the central waas and one other waas to test the upgrade? I have one waas remote at about 90 miles so I can get there in case of disaster. I want to wait on the others to make sure there are no problems. We are using all wccp redirection and virtual blades
