Transfer two websites from two hosts onto a new host

This project is fairly straightforward but still needs a bit of explaination. It's actually a merging of two separate hosting accounts onto a new web host. I have a test website on my Hostgator account ( [login to view URL] ) that I set up for a film festival called The Dam Short Film Festival. I need to move that wordpress site from my Hostgator account to my client's Hostgator account. We also need to move the film festival's old website ( [login to view URL] ) from it's present web host (Host Assured is the name of the host) to the client's Hostgator account. Finally, I'd like to make a subdomain for the old Dam Short Film Festival; so the Wordpress website would now use the [login to view URL] domain and the old non-wordpress site would have the domain [login to view URL] . Essentially, this is the list of steps to be taken: 1. Move the Wordpress site from my Hostgator account Client's Hostgator account. 2. Move the old site Dam Short Film site from HostAssured to Client's Hostgator account. 3. Change the DNSs to point [login to view URL] from Hostassured to the Client's Hostgator account. 4. New Wordpress site should be on Client's Hostgator account as [login to view URL], old site should be on Client's Hostgator account as [login to view URL]
