After setting up MultiDomain and Plugins, could I then Change the Domain name I set everything up on

If I setup a Multi-Domain and set it up on http://www.PrimeDomain.com and later decide to change the company name http://www.PrimeDomain.com to http://www.AnotherDomain.com so that plugins such as blogs directory, Members Directory, Pro-Sites, and WHMCS now work for/Tied to http://www.AnotherDomain.com.

What would I need to do?

Thanks!
