To create an exact copy of a survey, click "Clone Survey" in the Survey Administrator. The cloning feature allows you to re-administer the same survey more than once without clearing the results from the first survey. When you clone a survey, you can include a different welcome letter, instructions list, and look & feel if you want to.
What is the advantage of survey cloning? Because you are asking the same set of questions, you can track the change in responses over time or among different groups of respondents.
