# Updating Scan & Shop

Keep the Self Checkouts flying.


  • Duplicate your JSM | Scan & Shop model and store it outside your workspace.

In case anything goes south, you will always have a restore point.

  • From the fresh copy of S&S, copy the CoreEngine script. (Inside JSM | Scan & Shop)
  • In your existing installation, delete the old CoreEngine script, and paste in the new CoreEngine script.

After updating, confirm that the Scan & Shop boots and functions without throwing any errors to the Console.
