How do I pass Achievements and Gamer Score from one of my Profiles to a newer one of my Profiles?

I just made a new X-Box Live Gamertag and Profile. I wanted to pass all the Achievements and Gamer Score from my old profile to my new one. My new one has 1 Month Gold for X-Box Live and my old one's subscription ran out. How do I pass Achievements and Gamer Score from one of my Profiles to a newer one of my Profiles?|||You can't. You can change the name of your Gamertag for a fee, but you cannot move Achievements.
