I have an ASA that is in a remote location, that needs upgrading, the iOS and configuration changes.
Is it possible to reset the firewall to factory settings and upon bootup it loads a script to create all the new statements needed?
For example a “config factory-default” and “reload save-config noconfirm”
It then boots up with a pre loaded script on the flash or disk configuring all the interfaces and vlans and everything else?
Has anyone ever done this?
