In order to import survey data into UW Qualtrics, you need a Qualtrisc survey, the survey needs to match the format (type of question, etc) and the data format (date, string, currency, etc), of the old survey.
UWIT administer's the University of Wyoming's site license for Qualtrics, a robust survey tool that students, faculty, and staff can use for free with an active UWYO email address.
