2 Ways of doing this.
1. Test it by typing the old domain and see if it redirects.
2. Check the server headers from any tool like http://www.seoconsultants.com/tools/headers.asp

Go through the Sticky thread right at the begining of this forum and your questions will get solved but then also I will help you with the quotes from that thread.

You'll need to do a 301 redirect from the old domain to the new domain. Fortunately this is not difficult to do. You'll need to add the following lines of code to a file called .htaccess and place it in the root directory of the old domain:
Code:
RewriteEngine On
RewriteCond %{HTTP_HOST} ^(www\.)?old-domain\.com$ [NC] 
RewriteRule ^(.*)$ http://www.new-domain.com/$1 [R=301,L]

If you have a permanent redirect the things will slowly move and it will be a smooth transfer and theoretically nothing should happen to the rankings but no one can predict the practical aspects of it. Again I would suggest you to go through SEO FAQ's
