convert surveys from ASP.NET to limesurvey

I am developing an application for my website that involves two surveys, a database of survey responses, and sets of reports. The surveys have been created in ASP.NET, but I would like to switch to limesurvey. Phase 2 of the project will create the reports and develop a purchasing interface. The current phase is just to get the two surveys and database into limesurvey format.
