Not sure if anyone else ran into this.
ASA's security policies are built based on post-NAT rules (post 8.3 OS)
With the tool, it builds the same rules with the post-NAT rules, private IP ... which will not work with PAN as the rule is built based on post-NAT, public IP.
Is there an option in the tool to convert the IP to pre-NAT?

The migration should have used the post-NAT IP as the destination address in a corresponding security policy.
If you open the NAT rule then open the 'Security Rules Match' does the security policy show the pre or post NAT IP address?

The migration tool is building the security policy based on the private IP, post-NAT.
PAN matches based on pre-NAT, public IP.
In the NAT rule, the Security Rules Match does not have an entry. The first 4 reviewed has the same behavior.
What's interesting is that the migration tool prepends the NAT rule name with "Nat Twice" Not sure if there is a reasoning for it.

NAT-twice indicates its likely a bi-directional NAT rule learned from the ASA config. If you can share you config to:
fwmigrate@paloaltonetworks.com I can look at it.
