We are working on a SharePoint 2013 Environment. We recently made changes to the form template and published it. We are able to access the new template by opening up a new form from the Document library but the Issue is that it has also updated forms that were submitted previously to the document library.
I checked the Form Option (Versioning) settings in Infopath and it is set to "Do Nothing" to update existing forms. Not sure how the existing forms got updated. Anyways I really need to restore the existing forms to the previous version. Any help on this matter would be greatly appreciated!
