Hey Jason. I would be able to help you here but I am unclear on exatly what you are trying to do... From my understanding of what you have written you are just trying to get one of your sites, that I assume coupled in with a number of other sites, moved out into its own analytics account. It that right? If so then yeah its possible but you need to start the new account and you will lose all past data. You would be much better off just adding permission for the other account to have viewing access. If you explain your motives for doing this in more detail I am sure I can help you come up with the best solution.
Its got nothing to do with the site here. you just want to access analytic data from multiple accounts in'it ?That's quite as much possible by granting permissions and adding users to your own google analytics account.
