ASA 8.0 to 8.4 Exempt NAT

Hi All,

 

I am working on one of the ASA 8.0(3) to 8.4(5) upgrade and have a following question on exempt NAT conversion. I did upgrade and I am getting following result, I am not sure about it. 

OR is I should remove any any from ACl then do the upgrade?

OR is there any manual fix for it as there is no subnet requirement in ACL ( just any any )  ?

OR this will work as pre-upgrade function ?

These are twice nat entries generated by your nat 0 statement. It nats to
every exist interface.

any any in twice nat is matching any any ACL.

Thanks Mohammed :)

Does it mean it will work as expected. ( it wont do address translation for any IP address for mapped interface )

Does it require as pre-upgrade NAT 0 or exempt NAT/ no NAT will not do address translation ?

 

Yes its working as expected. Nat 0 doesn't exist anymore.
