Some lessons learned while doing a Trade-up of several FortiGates for satellite locations. After using the Forticonverter service the FortiGates (FortiOS 6.0.8 to 7.2.1) would not connect to FortiCloud and I kept getting errors about not connected to FortiGuard. All traffic stopped passing through the firewalls as well. Tried everything under the sun and everything that Fortinet Support told me to do. Nothing worked. It ended up being such a simple fix that I had to send it to Fortinet. Note to self: DON’T FORGET TO CHECK THIS
