Unfortunately, there doesn't seem to be a way to convert/change a SureTrak schedule to P6.8, but you can import the SureTrak file to Oracle Primavera P6.8. If you have both SureTrack and Primavera software installed on your computer, save the SureTrack file on your desktop as a P3 file and then open Primavera. From the File menu select Import, click Primavera Project Planner P3, browse for the P3 file, select it and press Open. Decide on Combine or Separate Projects, select the EPS position and follow the on-screen instructions. If you have problems, I recommend you check the first link from Google search engine.
