Do changes in top management require changes in the documentation?

Answer:

The documentation should reflect the current situation in the company, and the documents to be changes should be the ones directly related to the top management, e.g. Quality Policy. However, if the process procedures, policies, etc remain the same as they were before the change, there is no need to change them just to replace the name of the person who authorized them. The most important thing for each document is whether the approved version is on the place of application, not who approved the document.

For the documents you decide to change, you need to apply your procedure for document control. I assume that you procedure requires you to record the change in section "change of document", here you need to write what has changed and who made the change and when. Again, dependin g on the rules prescribed by your procedure for document control you need to perform withdrawal of obsoleted documents, the standard doesn't define how to do it so all you need to do is to follow your procedure.
