First Steps:

• If it wasn't already done, If you're using an IMDB (In-Memory DB), backup the 'imdata' folder to restore later.
  The default location is: "C:\Program Files\Pyramid\repository\imdata"

  "C:\Program Files\Pyramid\repository\general"
  This step should be done on each Pyramid server.

  (C:\Program Files\Pyramid\config.ini).
