If you have a mobile pass, you can do that yourself, since you only need to provide an ID number when you activate the pass. If you have already activated it, cancel the activation, so you can enter a new ID number. But do wait until the start day of your trip to activate your pass (again). There is no advantage in activating early, only a possible disadvantage, since you can only cancel activation until 23:59 CET on the day before validity starts. If something unexpected happens on your planned start date, then it will be too late to cancel activation. The same is true for activating a travel day (for a flexipass).

For a paper pass, or a mobile pass of which the validity has already started, the ID number cannot be changed. The best is then also to bring with you your old passport.
