Hello, we have been using Jaspersoft iReport Designer 4.5.1 for numerous reports in our company. Now, we would like to upgrade to a new version without having to recreate all the reports we made back then. Is this possible? We've heard about issues with main and subreports, as well as installing older compiler versions. What do we need to consider when transitioning to a new version, and how could we integrate the new version into our project structure?
