I was able to successfully transfer my domain from wordpress.com to DreamHost but to continue my migration to wordpress.org, will I have to buy the Happy Hosting Plan (which I purchased by accident), or is transferring my domain name the only thing I need to do?
If you want to host your own wordpress install then yes, you will need the hosting plan. Just go to manage domains and add your domain name to be fully hosted. Be sure the dns of your domain name are actually pointing to dreamhost nameservers.
Thank you for your reply. I will do this now.
