Presenter will explain the process and share our experience from a recent JES3
to JES2 conversion. We will review the prep work, including updates required to
the INISH desk, commands used, and the COLD start process. Migration steps
including adding JES2 to run under JES3 and the removal of JES3 from the image
will be covered. We will share examples, lessons learned, and gotchas we
discovered along the way.
