How to upgrade asa 8.2.5 ios to 9.2.3 ios and translate configuration from 8.2.5 to work in 9.2.3 IOS?

You cannot go direct to 9.2.3. Please review the guide below:

Hi ptran

I have just upgraded my first firewall from 8.x to 9.x but I did it manually with the help of a document from jouni forss.
