Its precisely what I do for clcients, spanning decades of experience in doing such. In as much as I can say I've seen single, dual and hundreds of co-locations moved with and without incident with stellar planning. Given DBGs past track record and hints about "not directly" and "36 hours" is enough to tell any reasonably competent engineer enough to come to the obvious conclusion as to what is about to happen and really shouldn't affect the server images, if at all unless someone decides to place a complementary patch inside the servers. Not going to torture this thread beyond what has been said on the technical side but will praise DBG for recognizing the problem(s) on the backend and doing something (hopefully well) but also recognizing that this is their business not mine, not yours to screw up. I wish them all the success in the world with this change, I really do. Thanks for the expert advice but I'll pass this time.
