Although I guess I already know the answer to this question, I must confirm if there is any way of updating an survey that is already online, without losing data. I have a MaxDiff survey that is already active, but due to new requirements, I need to update some things on it. Of course I don't want to lose the data already collected, so I'm asking if this is possible.
Alternatively, I could upload the new version of the survey to a different server folder, and have separate URLs for both, but that would imply a new survey design (right?), and I would need to analyze the data as a whole (old version + new version). I have SSI Web 7.026.
I hope I was clear enough, many thanks in advance,
