At this time, you would need to consult with us to do this import. The "utility" is really just a workaround until we can develop an official solution, so the data does need to be formatted correctly, and then the data is inserted directly to the database, so you would need to engage with our ProServe team to get this going. In anticipation of your next question, I don't have a timeline on when an official tool will be available.
Since the import tool only allows project profile import and does not include project content, any template material would not be included in this import process.
