We have a current form in use by volunteers. I have drafted a new form and want to use the same link as now.

I was going to go into the existing form and make the changes, but some of the fields are different, so I am not sure how it will effect the existing Queue??

Is it possible to change and existing page if it changes to format/fields in the Q??

Or do we just need to rollout the new link for use?

If you will edit a form that is currently being used, please note that if you delete fields that already collected data, their data will be deleted too.

If you want to build a different form, we would recommend you to clone it: https://www.jotform.com/help/27-How-to-clone-an-existing-form-from-your-account 

And apply the changes to the clone version, so the users can use the clone one.
