Yeah it is that simple Make sure you make those changes though BEFORE you point the nameservers and what have you.
The only other place that may affect your board showing up would be if you or someone else had put the pathway to your board in the place for the pathway. Most of the time this is not changed when someone is doing an install so it probably should not be a problem. If when you switch your domain and if you are running certain mods like say Photopost you will also need to change the URL in any and all mod that requests the URL in the settings before switching your domain.
The only other issue with switching the domain is to redirect your traffic to the new URL if you have a lot of traffic you do not want to lose. There are plenty of tutorials on creating a 301 redirect out there on Google.
