If you end up having to re-include all your devices you will need to follow this guide to get the old device DNIs out of the way before you start including devices. If you follow this guide you will basically swap the old device entry in the hub to the new DNI, preserving any rules/apps you have setup.
There is another way you can do it using Swap Apps (new since this was written) but I actually like the method in that guide a little better.
