Hi,
I have custom InfoPath form template published to the SharePoint form library. The client will create new InfoPath form based on aforementioned form template in this form library. When the form template is significantly changed (adding new controls, rearranging the controls) and resubmitted, the forms that were created using the previous form template will no longer work. Is there way to modify the form template but still be able to open the form created using the previous form template and at the same time these forms should have the latest changes made to the form template?
