In some of our old courses we wanted to implement a survey to get feedback from users. However, modifying the requirements to obtain the certificate and adding the survey as one of them, would imply that people who already got the certificate is now shown as that they have not completed the course. Also, they would need to complete the survey if they needed the certificate.
Is there any way to avoid loosing these data and allowing these people downloading the certificate even after this new requirement is applied?
Thank you very much for your time and help,
