converting domain into subdomain and pointing to domain

I have two domain registered, domain 1 & domain 2 Domain 1 is hosted right now and is up & running in open cart. Domain 2 is just registered without hosting. I have hosting for only 1 web site. I want to convert my domain 1 Into a SUB Domain of Domain 2, So that those who type my domain 1 get directed to it as a sub domain. On domain 2 i want to install woocommerce and run it as a primary domain. The work is 1. convert domain 1 into subdomain of domain 2 (Withtransfer of open cart content as it is and working into subdomain) 2. point my domain 1 address to new address as sub domain. 3. install woo commerce in domain 2 and make it as a primary domain.
