I don't think this is possible in many ways, but I thought I would put it out there to see if anyone had seen it done. Have a site with current GW system, version 8, and they want to build a new GW2014 system and move accounts from the old system to the new one. I can't think of a way to link the two systems to give this ability. Wanted to see if anyone else knew or had possibly seen this done.
