It is simple breakdown for a complicate firewall migration plan. It can be used to plan migration from existing firewalls to new Palo Alto Firewall. The tasks should be modified based on the real production situation in your environment.This is for on prem case. For cloud situation, the tasks will be slightly different. But most will be same.
