Transfer a subdomain to its own account


Apr 15, 2006
I've got a subdomain on my site that has its own domain. I've recently upgraded to a webhost account and I'd like to make the subdomain its own account so I can set up bandwidth limits and space and let the person who actually does the maintenance of the site at the subdomain have access to everything she might need. I can't find anything in the documentation or in searching the forums that explains how to do this. At least nothing that specifically states how to move an already existing subdomain.
