When a Version 5.5 image contains AbtMigrationApp, the Migrate >Base Migration menu choice is available from the Applications menu of the VisualAge Organizer. This provides a tool for migrating your work to Version 5.5.
To run the migration tool, select your application(s) in the VisualAge Organizer and then select Migrate > Base Migration.
While the tool runs a Migration Information workspace opens, indicating what classes migrated successfully. Note the suggestion printed to the workspace when the tool finishes running; it advises you to version and release migrated applications and classes and, if necessary, regenerate archival code.
When you finish migrating your work, you can unload AbtMigrationApp.
