Problems with NAT when we upgrade

[Waldemar Farinha Dias]

Hello Team,

Whenever we have wanted to upgrade from version 8.4/8.5 to 9.1 we have had problems with NATs and had to perform a downgrade. Do you know if there's a problem? With the vulnerability recently discovered we need to perform this upgrade.

Thank you.

Best Regards,

Hello @Waldemar Farinha Dias, 

Are you following the upgrade path for your version, maybe that´s the reason why you are having problems with the upgrade, check this link for reference: https://www.cisco.com/c/en/us/td/docs/security/asa/upgrade/asa-upgrade/planning.html

Hello GioGonza,

Thanks for your help.

I'd say I made the right "jumps".

In this case it looks like a direct upgrade (8.4(7)30 -> 9.1(7)20)

Thank you.

Best Regards,
