If you have applications and PowerBuilder library files (PBLs) that you created in an earlier version of
PowerBuilder or InfoMaker, you can migrate them to version 12.5. Before you do, make sure your PBLs can be successfully regenerated under the earlier version, and make backup copies.
PowerBuilder and InfoMaker 12.5 are Unicode enabled, and some changes are made to your code when you migrate an application from PowerBuilder 9.x or earlier. For details, see the section on migrating targets in the
PowerBuilder Users Guide.
Also read the migration issues section in the PowerBuilder release bulletin.
