I think I'm with 1138 on this one. Thinking back, really, it's the issues with dinosaur systems that I really NEED the most help with. And to the business, the fact that it's old and decrepit only means that it needs to be fixed more quickly - as it's obviously essential, or why else would it not have been thrown out years ago?
Yes, that was said somewhat tongue-in-cheek - but also with a violent shudder. Supporting - to put it diplomatically - legacy apps & hardware can be agonizing, and if the questions are going to exist on the Exchange at all, they may as well be in the proper forum.
Aside from all that, I think it makes sense to migrate things around as the lines between sites become more clear. A natural and healthy development of the system as a whole (very appealing to my OCD side).
