How do I transfer all services to my new email account and close the old one?

I purchased a domain from yahoo and use a different email account to control it. I want to transfer all services, ie. mail, contact address, my premium upgrade, etc. from the old email account to my domain email account, notify my contacts of the change, then close the old email account. How do I do it?
