InfoPath Dev

We have a Info Path Form that we digitaly sign and store on a Sharepoint Windows 2007 Form Library.  Everytime we want to make a change and publish the template, it updates the already existing forms and invalidates the signatures.  Is there a way to save the existing forms so they don't update the already saved forms when we update the template?  Also tried copying the form but since linked it also updated the saved form in the new location.  There is an option to break the link but too many steps.  What is the correct way of doing this?  Thanks.

Sorry to doulbe post in different sections.

Follow the below steps which will not update the existing form s

2.Go to Tools Menu
3.Select 'Form Options'
4.In Form Options wizard, select Versioning present under 'Category'

 Perfect, I think this will work fine. Thanks!
