I know this in an unsupported configuration, but I have a bunch of old
firewalls that are running 6.4 firmware and no matter how hard I push, I
haven't been permitted to upgrade them. We will be swapping out hardware
soon to new firewalls but that is...
My company decided to downgrade the firewalls that are running 7.4.1 to
7.2.6 and upgrade the FortiManager to 7.2.4. Thank you for your input.
The compatibility matrix helped make the decision.
