So does that mean that everything up to the oath, such as executive orders, have to be reissued?

LOL. You raise an interesting point.

No. The 20th Amendment made him pres at noon on the 20th, oath or no. And according to what I've read, some Presidents in the past just said "I do" and didn't repeat the oath at all.

It should, the Constitution requires "Before he enter on the Execution of his Office, he shall take the following Oath or Affirmation:". But they probably won't bother, and it really wouldn't matter, how hard can it be and how long can it take to reissue the orders?
