After your domain sucessfully change to new one, then add your co.cc domain to addon domains.
Then go to "Redirect" Option in cpanel and set wildcard redirect for co.cc domain to main domain
At the moment we need Account Manager to change your main domain.
I have requested Account Manager to look into this, they will get back to you soon.
Go to co.cc and setup a wildcard redirect to your new domain.
