Moving installation from subdomain to root domain?

[LDDG]

Quick question,

I currently have my IPS Suite installed in a subdomain (http://subdomain.mywebsite.com).

If I wanted to change everything to run off of http://www.mywebsite.com, is it as simple as moving the entire installation folder/files to my root folder and making the changes to root folder within the config.php file to point to www.mywebsite.com?

Or are there other changes I need to make?

Also you probably have to change the .htaccess file. Replace "/blahblah" with "/"  for example
