Once I saw the upgrade cleared, I simply got up, walked to the newly assigned J seat, and asked the FA for a new boarding pass.
She just said (paraphrasing): "I can get you a new BP, but it may take a while, as I have to go and ask the GA for a new one."
Happy with my new seat, and not wanting to delay the flight, I simply said "Nah, don't bother, but thank you though", made myself comfortable and enjoyed the 13 hour flight in comfort. ^
A new boarding pass isn't ALWAYS issued!
