I'm no dealer, but i'll give you my experience. I had my main controller crap out. my dealer sent me a new controller and identified it remotely. He remoted in to my computer installed composer pro, and I pressed the identify button when he told me too. He then installed the newest version of composer pro (2.5) at the time and updated my OS version. It may not be part of best practices but it can be done and I bet some of the dealers on this forum would have no problem helping you out.
