I have a wordpress mu site set up to use subdomains and i would like to change the domain of one of the sites on the subdomain from http://site1.example.com to http://www.example2.com. I go to the network admin menu, sites, and edit the domain name of the site telling it to "Update siteurl and home as well." the site url take and so does the home but the domain name does not. any ideas where this is located so i can edit it manually or any ideas what is going wrong so i can fix it?
