Reset vera 3 and start from scratch

Hi All

Quick question, I have recently moved bringing my Vera 3 with me and some of my devices, some were left behind so I can not exclude them. This has left me with a lot of holes and nodes that showed used but I no longer have, so my plan is to exclude all the devices I have then default my Vera 3…
Here is the question part, I have a main house with a large detached garage and a small accessory building, what is the best order to learn my devices back into the system… Closest to my Vera headend in the main house or from the farthest point and work my way back or does it matter at all?
