For any cutover event, especially when dealing with network security infrastructure like Palo Alto

Networks firewalls, it is critical to ensure that:

Change Management Requirements (B): This involves verifying that all planned changes have been

approved, documented, and communicated to all relevant stakeholders. The change management

process ensures that any modifications are controlled, predictable, and include a rollback plan in case

of issues. Reference: Palo Alto Networks Best Practices for Change Management Documentation.

Roles and Responsibilities (C): Clearly defined roles and responsibilities ensure that everyone

involved knows their specific tasks during the cutover. This reduces confusion, ensures accountability,

and helps in the smooth execution of the cutover plan. It includes defining who is responsible for

specific tasks, who needs to be notified, and who has the authority to make decisions. Reference:
