Moving the Uverse DVR

The original install location of the DVR was in the living room, with TV1.  That space will be under construction soon and I want to move the DVR from TV1 to TV2, and put the TV2 box in "storage" until the work is done.  It would then be attached to TV1.

I can't find anything about doing this, but when I had some trouble with the original DVR, one of the questions asked was if I had moved it.

Which would imply there could be issues if I do this with proper preparation.

So what should I be doing to make this successful?
