Change of Project's Domain

Change of Project's Domain

Hi;

When I try to change the domain of our projects I see the following alert:

" Sorry. Portal Owner Change option is disabled for Google-Apps Domain Portals."

We are moving our team to another domain, main corporate domain, and as such want to disassociate the account from Google-app portal.

How can this be done?  I sure hope we don't have to abandon this and start over.
