Hi,
All cluster units must be the same FortiGate model with the same FortiOS firmware build installed. All cluster units must also have the same hardware configuration (for example, the same number of hard disks and so on) and be running in the same operating mode (NAT mode or transparent mode).
I hope this helps to answer your query.

Hello, 

thanks for the clarification. 

just want to confirm these below also apply on KVM/Vmware fortigate vm right.

this article making me a lil confused:-

FortiGate-VM HA supports having two VMs in an HA cluster on the same physical platform or different platforms. The primary consideration is that all interfaces involved can communicate efficiently over TCP/IP connection sessions.
