I did or rather, GH did it for me. Took an hour. I traded in my premium for the elite last year after it severely scratched my Oblivion and Halo 3 LE. While waiting I drove home to take money to pay for the sku upgrade =p There was a side effect though. My Halo 3 save file didn't work and I had to start the stage again (I wasn't very far off anyway). Every other game has been fine.
