Yes! Just open your file in Castaway 2019 and get to work. the first screen you see is the new Overview dashboard.
You don't need to make any changes, because Castaway takes care of everything in the background.
Of course, you might want to take advantage of some of the new features we've added. Maybe add some new dashboards using the new preset dashboards feature, or add your brand to reports.
