Thanks for clearing that up Scott. However, my situation is that:
1 ) I have a blog, blog.abc.com.
2 ) I want to migrate that over to a WP installation at Dreamhost, eventually using the same URL.
3 ) I want to be able to setup wp and everything prior to pointing the URL to DH. Say, by creating & hosting testblog.abc.com on DH.
The problem with that is I don't want everything to be installed and associated with "testblog.abc.com"
So here's what I did:
1 ) Setup DH to full host abc.com.
2 ) Created a sub domain of abc.com, blog.abc.com.
3 ) Setup WP via goodies to be installed into blog.abc.com
My question is, what do I do now? Can I someone associate another CNAME with the blog.abc.com WP installation?
