But how long before, I can't guess.
I believe the credit card number doesnt actually change on upgrades. So my own expectation was that I could make one purchase on my old card as soon as I upgrade to get the bonus.
While I have no direct experience with Chase in a similar situation with Amex I get all my SPG Luxury benefits even though I am using my old card.. and expect to not receive my Luxury card for a long time due to shortages at Amex (over a month now)
