We have a domain with URL, lets say: http://www.xxxxstaging.com/abc.php?id=10
which is having a pretty good ranking for some keywords in google.
However, this is our staging website and due to some historical reason, it was exposed to public.
Now we have a production domain (the one we want to be publicly available), say: http://www.xxxxproduction.com/abc.php?id=10
which have exactly the same html output as xxxxstaging.com
our question is, for the exactly same keyword search, it never appear in any page of google.
Is it possible for us to "switch" the ranking in google, either tell the robot that they are indeed the same website, or tell google to change it for us?
