downgrade Cisco ASA IOS

Hello folks

I am looking to downgrade software on our Cisco ASA 5512-x firewall from 9.12 to 9.11 (dont ask me why, I was told to do so), is there any precedures doing so?

 

would the running-config currently on the firewall be affected by the downgrade (or upgrade)?

 

Thanks

As long as you aren't using

As long as you aren't using any of the new features specific to ASA 9.1(2), downgrading to 9.1(1) would not affect the running-config.

Simply copy the new image onto disk0: and change the boot system variable to reference it. Save and reload.
