During the migration from FortiGate to Sangfor Firewall, it is recommended to prioritize the use of automated tools for converting network objects, service objects, security policies (ACLs), and NAT policies.

These configurations not only form the foundation of the entire security policy framework but are also typically large in quantity and have complex interdependencies. When migrated manually, they are prone to issues such as name conflicts, missing references, or incorrect policy order.

Automated tools can efficiently and accurately map objects and policies while preserving the original structural relationships, significantly reducing manual workload and configuration risks.

In addition, the accurate migration of network and service objects provides a stable dependency foundation for subsequent modules such as VPN, Application Control, and User Authentication. Therefore, it is strongly recommended to complete the above automated conversion steps before performing manual migration of other modules.
