Domain Mapping Plugin Setup With GoDaddy Registrar

Hello, sorry for the novice question but I currently took a site that I had setup on my VPS and deleted it from WHM so the site no longer exists. The site is still pointing to my name servers in GoDaddy. The site is iowapgafoundation.org.

I created a new multisite network and everything is working correctly. The new site is built (www.foundation.iowapga.com) and I am ready to point the existing domain in GoDaddy to the new site that I have created in my new multisite account.

I have setup the domain mapping tool and everything looks like it is working properly in there.

My question is, do I need to setup a new account in my VPS on Hostgator for the iowapgafoundation.org domain or can I simply input an A name in GoDaddy domain registrar to point to the server IP?

Any instructions would greatly be appreciate. Love the plugins and thanks for your help!
