Perhaps I misunderstood the point of your post, but in case I didn't, it might be best to remind people that while D fares can be upgraded, I fares cannot. Not with miles. Not with VIPs. There's an argument that perhaps they can be with a certain BusinessExtrAA upgrade cert, but nobody has yet reported success with that animal. Suffice it to say - the OP's cert won't work on an I fare.
