Hi,

Moving from 8.2.5 to any version higher would require many configuration changes.

Refer to this for more information:-

Also , I would recommend upgrading the ASA with 8.0.5 to ASA 8.2.5 as ASA 8.0 is EOL:-

This should be a minor upgrade.

Upgrading from the ASA 8.0.5 to ASA 8.2.5 should be minor.

Do you have two ASA unit running 8.0.5 that you would be upgrading or is it a standalone device ?

Hi,

I think you should check the document that i gave you previously if you want to upgrade to any version higher than 8.2.

For the ASA device upgrade from ASA 8.0.5 to ASA 8.2.5 , you should not have any issues.

Thank and Regards,
