You can migrate a PowerBuilder application from any version of PowerBuilder directly to PowerBuilder 2019. You cannot migrate applications from PowerBuilder 2019 to older versions of PowerBuilder.
Before you migrate, 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.
Note
The "Migrating PowerBuilder Applications" technical document at https://www.appeon.com/support/documents/appeon_online_help/pb2019/migrating_pb_apps includes information on changes to PowerBuilder since version 6.5 that might affect the conversion of applications to a more recent PowerBuilder version.
