wordpress.com subdomain to ww.wp.xz.cn subdomain

I currently have a blog hosted at wordpress.com with a my own domain (i.e. blog.exampledomain.com). I’ve set up a subdomain on my own host with the same name and done the ww.wp.xz.cn install but haven’t pointed there yet from the current location.

The problem I’m having is the admin URL of blog.exampledomain.com/wp-admin gets me to the wordpress.com admin section rather than the new ww.wp.xz.cn install.

Can I access the ww.wp.xz.cn install (so I can import content from the current blog) without pointing blog.exampledomain.com to the new self-hosted location yet?

Thanks in advance!
