Are you referring to moving from a WordPress.COM blog to a WordPress.ORG install? If you are then install the Jetpack plugin and activate it, then post both URLs into this thread as Staff can do this for you.
if your are referring to moving a self hosted WordPress.ORG install from one server to another we cannot help you here. This support forum is only for those who have free hosted WordPress>COM blogs and that is not a free hosted WordPress>COM blog.
If you don’t have a username account at WordPress.org, click http://wordpress.org/support/ and register one on the top right hand corner of the page that opens, so you can post there.
