domain migration from WordPress.com

I started with a WordPress.com free site. I anted up a few bucks to WordPress.com for my own domain name, let’s say https://myexampleblog.com, to use rather than https://myexample.wordpress.com.

Now I’m moving up to a www.remarpro.com installation on my own server site. I’ve installed in a subdirectory of the main one for my own other main site: myexample.net/blog.

So using https://myexample.net/blog opens up the new www.remarpro.com installation, but I’d like to be able to use https://myexampleblog.com as the URL instead…I own it after all.

I did a whois search and found that myexampleblog.com is registered at wildwestdomains.com but their website doesn’t say anything about domain registration support.

How do I get the myexampleblog.com domain name to point to the new installation?
