WordPress.com>wordpress.org

First I had a blog on wordpress.com, for which I paid for domain mapping and acquired the domain: whatshesaidstitches.com

I have since exported/imported that site and it is now hosted elsewhere as a wordpress.org site.

Now I need to have the domain name switched to that new .org site and I don’t know how to proceed since I purchased the domain via WP.com. How do I change the DNS server info?

I have other domains with godaddy.com. Do I move the domain there first?

I’d appreciate any help, thanks.
