Can I edit my questionnaire and redeploy after collecting some data?

Can I edit my questionnaire and redeploy after collecting some data? Is the already collected data safe after I redeploy?

I would be grateful for a response

@brunonatu, yes it’s safe but I would advise you to make a dummy project and make some dummy actions to that dummy project to see that your data is safe on the server. We also have a support article Recovering Data From Previous Form Versions that should help you understand more about how to recover your data in such cases.
