If you want to clone a form from another account into yours, simply get the URL of the form, and then clone it in your account: https://www.jotform.com/help/42-How-to-Clone-an-Existing-Form-from-a-URL 

If you actually need to transfer the form and it's collected data to another account, the request needs to come from the username that currently owns the form, and it is necessary to specify which form will be transferred, and the account username that will receive it.
