Does changing the order of questions reflected in past quiz results too?

I have two quick questions about implementing the quiz module:
1. I have the questions in a particular order and about 100 people have taken the quiz. We have implemented the quiz results download module. If I CHANGE THE ORDER of the questions (make question #3 the new question #1) will the results (old one in particular) automatically UPDATE or will we have ‘MIXED’ data – some with the old question numbers and some with the new ones?
2. As you know, there is an option to present responses (answer choices) in random order. We had NOT checked that box. If we now check that box, will the old data get automatically updated?
