Normally, the IOS upgrade will leave your config intact.

The hard part will be implementing the firewall rules.

I suggest you first deploy them on secondary HSRP router and test them with two computers, one on each side ( both pointing to the physical IP of the secondary router).

When the rules are ready, copy them to the primary.

Please rate if this helped.
