I think you could achieve it by populating the data in your second form with the fields configured as read only.
To do it just follow this guide : http://www.jotform.com/help/71-Prepopulating-fields-to-your-JotForm-via-URL-parameters
You can then add the link in the Thank You Page or simple redirect it automatically to this form with the prepopulated data, follow this guide for further assistance related to it : http://www.jotform.com/help/211-Setting-Up-the-Thank-You-Page
Do let us know if you have more question in regard to your request, we will be more than happy to assist you.
