For those who have upgraded a Venture One card to an X, do the existing AUs carry over? I intend to keep the VX indefinitely, but since my wife is already an AU on my V1 card, I'm thinking of closing the current VX and then upgrading the V1 to VX, so that she does not get another card on her record. Is there anything that could go wrong with this plan? Is there some way to time it so that the new card year is the same as the calendar year?
