I've got another review system but I would like to get Revi, Is it possible to keep all my previous generated reviews?

Almost all five-start-rating-system will allow you to export all the reviews before cancelling the plan you have contracted. By providing this information by a CVS or Excel, we will be able to add them into your Revi's subscription. However, we will inform users that all these reviews were not verified by our strict control system.
