Here's a quick snippet of code to keep around if you ever migrate from an old domain to a new domain.
Shown here is what I used to move brantwynn.com to whaaat.com:
<IfModule mod_rewrite.c> RewriteEngine on RewriteCond %{HTTP_HOST} ^brantwynn.com$ [OR] RewriteCond %{HTTP_HOST} ^www.brantwynn.com$ [OR] RewriteCond %{HTTP_HOST} ^www.whaaat.com$ RewriteRule (.*)$ http://whaaat.com/$1 [R=301,L] </IfModule>
This not only redirects to whaaat.com from brantwynn.com but also bumps off the www. subdomain
