Initially we had a browser enabled Infopath form built in Infopath 2007, which was simple and without any code. We published it to a form library and users have been using it to submit forms and there are about 500 forms.
Now due to some business requirements we had to update the form add more fields include VSTA. And now we published and got it uploaded by our Admin to SharePoint, now we want users to submit the form using the new template(or content type) and also able
to open old forms using the new template.
