I am building a WP site on my own server. The client has an existing site on another server and does not want to have any down time. I would like to build this site on my server using a generic production domain name - Example: production1.com - and once I am finished, I will change the domain name on my server, to his. At the same time the client changes his name servers to point to me.
Is this the correct way to do this? Is there a better way? Exactly what will I have to alter withing the WP site itself?
Thanks for the help,
