You can use your source control manager to check out all the old PowerBuilder objects to a named directory or folder. If you plan to use the same project to store your migrated objects, you must make sure that the manager locks the files you check out of the source control archive.
You can create a new target using the Application target wizard in a new or existing workspace. The Application wizard lets you select or name a new PBL file to associate with the target it creates. You can use the Target property sheet to list any additional PBLs you want to associate with the target.
You can then import the files that you checked out of source control, distributing them as needed to the libraries you associated with the new target. After importing the files, you can migrate the target by right-clicking it in the System Tree and selecting Migrate from the target pop-up menu. You should also do a full build of the target. After you have migrated and built the target, you can define the connection profile for the workspace to point to the old source control project if you want to maintain it, or to a new source control project if you do not.
