Yes. Just note that if you use the organizer to 'convert' a current catalog, a new catalog is created from the data in the old one. The old one is renamed with a +-1 suffix and works as before with the old version. However, if you start to add photos and organize in the 2018 format catalog, the new additions will be lost in the old catalog. No backward compatibility. Better use the old organizer until you are sure to buy 2018. You'll convert manually when you are sure.
