Upgrade Information

You can upgrade a PowerBuilder application from any version of PowerBuilder directly to PowerBuilder 2019 R2. You cannot downgrade applications from PowerBuilder 2019 R2 to older versions of PowerBuilder.

Before you upgrade, back up your files and use the Migration Assistant to identify obsolete code. The applications you build using the current version of PowerBuilder must be deployed with the PowerBuilder runtime DLLs from the current version.


The "Upgrading PowerBuilder Applications" technical document at https://docs.appeon.com/pb2019r2/upgrading_pb_apps/index.html includes information on changes to PowerBuilder since version 6.5 that might affect the conversion of applications to a more recent PowerBuilder version.
