Introduction to Firepower_Migration_Tool_v2.3.3-5260.exe

This Windows-based migration utility enables seamless transition of security policies from legacy ASA (Adaptive Security Appliance) platforms to modern Firepower Threat Defense (FTD) environments. Officially released in Q4 2024, version 2.3.3-5260 introduces enhanced compatibility with Cisco Secure Firewall 3100/4200 Series and Firepower 2100 appliances running FTD 7.4.1+.

The tool automates conversion of access control lists (ACLs), NAT rules, and VPN configurations while preserving audit trails – critical for financial institutions and government agencies requiring compliance documentation. Supported source configurations include ASA software versions 9.16+ and Firepower Management Center (FMC) 7.2.x deployments.
