VisualAge Generator to Enterprise Generation Language Migration Guide

Improving performance

To minimize the memory usage, it is best to clean up (or "scrub") the image before running the Stage 1 migration tool. To clean up (or "scrub") the image, do the following:

  1. From the System Transcript, select Tools --> Open VAGen Tools Workspace.
  2. Under the "Image Management" section, swipe through:
    System abtScrubImage
    
  3. Then right-click and select Execute to run System abtScrubImage.
  4. If you scrub the image, you might need to reload the VAGen EGL Migration feature. See Loading the migration feature for information on how to load the feature. Alternatively, to add the EGL Migration Tools option back onto the System Transcript tool bar, do the following:
    1. Type the following into the System Transcript window:
      HptEglMigrationGuiApp loaded
      
    2. Swipe through the line you typed, then right-click and select Execute.

To reduce the time the Stage 1 migration tool spends analyzing which configuration maps and versions to migrate, consider creating a library that only contains the configuration map versions that you want to migrate. If you have ongoing maintenance in VisualAge Generator while you are migrating, a separate migration library also has the following advantages:
