I had cloned a form (with several improvements), but I want to keep the same URL, is this possible?

To avid to inform to all our users about the new URL, I would like to keep the same URL

Once a form is created it is assigned an ID number that cannot be changed.  You can customize the URL:

But the underlying form ID would still remain the same.
