Site Moving Issues

Hello guys

In attempting to move one domain to another (demo.emagenationstudios.com) to a new domain (adameveshop.com)

We went about the process all wrong by following the following steps.

1. Changing the WORDPRESS ADDRESS URL and the SITE ADDRESS URL on the first site demo.emagenationstudios.com from demo.emagenationstudios.com to adameveshop.com

Now I can’t log into either of the site I NEED URGENT HELP
