I have booked from Paris to Frankfurt on the Ice 10.52am from Paris Est on May 30th. We now have the opportunity to meet some French friends so want to push the time back. I went in to my DB portal to change the time to 13.51pm on TVG and got the message below. Is there ever a problem getting on the train with updated reservation/ticket?
