FortiOS Upgrade Experience and Recommendation
In our network we have a mix of FG200D, FG60E and FG200E firewalls all managed by a single FMG VM. Currently we are running latest version of 5.4 across all devices and FMG.
In the past we have been reluctant to move to the latest major release, at least until after a few minor releases to fix bugs. Taking this into consideration, we are contemplating upgrading to the latest of either 5.6 or 6.0 and would like to know your experience and recommendation. Are there issues with 6.0 making it more sensible to go the 5.6 route, at least for now?
Your time is appreciated.
