Upgrade Multiple RSAs as Action from Remote Sites Screen
When you manage multiple RSAs, it's a pain to upgrade all of them when you finish an upgrade of the master appliance.
From the remote sites screen on the master appliance, you should be able to check the box next to multiple RSAs, and choose Upgrade Remote Site from the Action dropdown.
