How can I copy and update an existing survey without losing/discarding the previous version?
When you go to Create Survey, you should get a pop up box and first, name your new survey, then in the bottom half of the pop-up it gives you an option to “Copy a Survey.” Select that and then name the survey you want to copy.
A word of warning, if you copy reports, then make changes to the questions, the copied reports will have some issues. We initially copied reports, but then I ended up deleting them and starting fresh because we made too many changes.
Hope this helps!
