Which action can help alleviate a prospective customer's concerns about transitioning from a legacy firewall...

A. Discuss the PAN-OS Policy Optimizer feature as a means to safely migrate port-based rules to application-based rules.

PAN-OS includes thePolicy Optimizertool, which helps migrate legacy port-based rules to application-based policies incrementally and safely. This tool identifies unused, redundant, or overly permissive rules and suggests optimized policies based on actual traffic patterns.

Why Other Options Are Incorrect

B:The migration wizard does not automatically convert port-based rules to application-based rules. Migration must be carefully planned and executed using tools like the Policy Optimizer.

C:Running two firewalls in parallel adds unnecessary complexity and is not a best practice for migration.

D:While port-based rules are supported, relying on them defeats the purpose of transitioning to application-based security.
