Identify business-critical applications that rely on these firewalls, so that those applications can be verified post-upgrade.Ĭisco ASA failover allows for the synchronization of some stateful information such as NAT translations, TCP/UDP connections, ARP entries, ISAKMP and IPSec SAs, remote access VPNs, and other features.This can help guide any verification procedures that should be performed.
Review any design documentation that you have for your implementation.Also review this software compatibility matrix if you are using any additional tools (e.g., ASDM) or modules (e.g., FirePower Module).
