Best Practice-New/change to test question

Hi all! We use Qualtrics to administer tests to associates. The results are displayed using dashboards. What's the best practice when: 1. A test question has changed completely? * Do you delete the old question (and associate data) and add the new question and update the dashboard widgets? * This will make the scoring on old tests/dashboard widgets incorrect as those users answered one less question. * Keep the old question but add the new question (which it tells me is now changed and not mapped correctly)? 2. A test question stem (question) or options (responses) have changed? * Do you update the old responses manually to be the new responses if they got the question correct on the old wording? * Do you delete the old question (and associate data) and add the new variation of the question? * This will make the scoring on old tests/dashboard widgets incorrect. What is the best practice that you follow? Are there qualtrics job aids / help guides for what to do when this occurs? If so, can someone point me to them? I haven't located anything. I appreciate any guidance. Thanks!
