I have site a. www.sitea.com I want to change the domain name to www.siteb.com due to some expanding niches. I still want to have the domain www.sitea.com be available and not have broken links from external sources like google, forum posts, blogs, etc. Any easy way to do this? Not sure if a simple redirect will work. Will adding the domain as an addon domain and pointing it to the same domain in cpanel work?
