You must upgrade PBLs created with earlier versions of PowerBuilder to the new version. You should always back up PBLs and PBTs before you upgrade.
The Migrate Application dialog box opens automatically after you open a workspace that contains PowerScript targets built using an earlier version. If you add a PBT containing such PBLs to an open workspace, or add PBLs built in an earlier version of PowerBuilder to a target's library list, the Migrate Application dialog box does not open automatically. To open the dialog box, select each target that contains PBLs created using earlier versions of PowerBuilder in the System Tree and select Migrate from the pop-up menu.
Perform a full build to PBLs after they are upgraded successfully.
Please read the section called “Upgrading targets” in Users Guide before upgrading your applications.
