In my current scenario, i have got 3 versions of the same template : v1, v2, v3. I want to change the form template from v1 to v3. How can i change the template based on versions for a form?
It is probably best if you ask your template designer to arrange this for you.
A form will use whichever version of a template has been published to the library and so this may be as simple as publishing v3 of your template to the right library. However, it may be more complicated depending on your library set-up and if you want different forms using different versions of the template at the same time.
