The first site I managed when I started working with sites 10 years ago wanted us to move their high traffic site. I was terrified of all the things that could go wrong. So I made a list of everything that could go wrong and of everything I would do to ensure that failure mode would not happen. It probably made the process much more complicated than it needed to be but we managed to move the site without any problems. I can recommend that as a method.
