Well, the only thing i can say is, i hope you didnt pay to far ahead on your xbox live, cus all i can think of is take your other account online.

It is not possible to transfer achievements from one gamertag to another.

u cant transfer it
halo 3 isnt hard
especially if u do on xbox live
i finished legendary with all skulls in about 9hrs on xbox live with mates

I don't think it is possible to transfer over.

What the other says is true, you can't transfer. What you should've done rather than making a new gamertag was log into the account that had all the achievements and etc and gotten that account upgraded to a live account. You can still do that by the way, but you're going to have to pay for that one again.
