Has anyone successfully upgraded from 10.1 to 10.2 on AWS manually? Not using Cloud builder? In the manual if not using cloud builder it advises doing a "update directly" I checked with Esri and they said yeh, upgrading using the 10.2 software like any other non cloud non AMI setup was the way to go. It hasn't worked, it's not functioning, there is a windows service called arcgis running but I can't contact it or manager. The log kicks out "Failed to unregister Amazon EC2 instance from the site", any ideas appreciated. - Dan
