Agreed, switching dns can be daunting. If you do it as fast as possible, there isn't anything special you should have to do. If you are moving the entire site - say to a new host - then leave the old site there 24hours longer than you think you need to. If your bill is paid up through the end of the month, then leave it at the old site a week longer and then put up a redirect on the old ip.
