Easy migration to new routers

I agree with the basic sentiment here, in that migrating from on generation of router to another, and as guy working in IT, I know that if you provide a migration technique to assist in staying with the same vendor then this is a strong selling point. Apart from moving across the settings, there is the issue that it is often the case that the simplest method involves having both routers active at some so point so that there is no interruption to services while you get the new router sorted out, and you can migrate one client device at a time if necessary.
