Run the scripts in DEV.

• If errors occur while executing the script, cancel the script and save the output to analyze the errors and fix them. Resume running the script until no errors.

To move these changes to Acceptance / Production, open a change request (scheduled for, at minimum, 3 business days later).

• Acceptance change: Script will need to be sent to DMI team for review.

• Production change: In the plan, indicate that DMI will need to get the script from the ACC change.
