Fortigate 40C and 5.2.13, to upgrade or not?
Greetings Tech Wizards!
Been a partner a few years and I have a number of older models. Most are 40c or FWF 40 or 60 C. Prior to joining FortiCloud I had upgraded one beyond 5.2 and had high CPU issues and had to roll back. I have some newer units on the newer OSs and I like the features, but not having them has not been horrible. Most of my clients are Small Business and I keep them on current contracts with Intrusion Prevention, Spam and AV etc.
My question: Is it safe to stay on the older OS as they haven't done any patch for this in a while?
Thanks!
Tom
