I have 2 sites in a multisite environment. one is www.mycompany.com installed at
public_html/mycompany.com main directory of the drupal core and uses
I have another site www.sub.mycompany.com using the folder
I want to change their domain names. I want www.sub.mycompany.com to be in www.mycompany.com and want www.mycompany.com to be in www.sub2.mycompany.com
so www.sub.mycompany.com won't be used anymore
how to do this?
