SharePoint - move a site from Central Administration

I recently took over a MOSS setup. When it was initially configured, they created the first site collections and workspaces in the Central Administration web application. I am trying to move these sites (that have a lot of information in them) to the default "SharePoint - 80" web application. I installed Batch Site Manager assuming it would allow me to move the sites like any other, however, the BSM does not show site collections under the Central Administration web application. Is there another way to move these sites?
