All you have to do is re-link your XBL gamertag to your new Bungie account. Then, leave the bungie account you are using alone, and let it die.
Now this will take you some time seeing as how you use your current email to talk with others. I'm sorry to say that you'll have to copy your friends' emails, and then put them as new contacts with the new email. I'm sorry its a burden switching to a new email.
