I'm trying to upgrade from 6.4 to 6.5 and have created the task but it sits there with "Execute ASAP". I suspect it's because the ERA can't see the server (they're the same server) because i have to manually add it to the list of computers and it shows as never connected. I have confirmed the agent is installed and tried all the usual reboots, service restarts et. but nothing works. Any ideas? I just trying to upgrade to management center!
