To archive questionnaires, there are two options:
- Download the PDF or HTML version of the questionnaire from Designer
- Download the JSON version of the questionnaire loaded onto Headquarters via this API endpoint:
But, to my knowledge, there is currently no way to create a new questionnaire from these archives.
An additional option: make the final version of the questionnaire public. When folders were added to public questionnaires, there was an idea that institutions might create and populate folders with questionnaires to be shared freely within their organization and with other users. Public questionnaires can be cloned by anyone, and altered/updated as needed.
These solutions may not be exactly what you have in mind, but hopefully give you ideas of reasonable workarounds while waiting for the ideal feature.
