Hi

I am preparing to move my Blogger blog to a WordPress hosted site at BlueHost.

How do I create a mirror domain that I can use to setup and test the site, and then later switch DNS records when I'm ready.
I.e.
Create DNS entry in domain manager for blog.foo.com
Blog.foo.com DNS is externally hosted, and DNS record points to active Blogger site not to BH
Create mirror DNS entry, using a BlueHost domain name, pointing to the same site as blog.foo.com
Install WordPress at blog.foo.com
Configure WP using mirror domain
Test mirror domain
Transfer DNS record to point to BH server or mirror CNAME

Some hosting providers have domain names that they control, but let me create a subdomain to use for mirroring or for CNAME assignment.

Does BH offer such a service?

P.
