Problem moving WP from one site to another with url/domain

I built a wordpress site for a friend on my domain, hosting, and database, and have tried to move it over to be under my friends url/domain. I followed all the steps (I believe) that WordPress provided including exporting the SQl file and importing it to the new location. The home page works but when I want to go to another page or even log into the admin panel, it reverts back to the old domain. How do I fix this so its all under the new domain?

The site went from goodvibrations.calhans.com to www2.goodvibrations.org
