FortiGate Next Generation Firewall utilizes purpose-built security processors and threat intelligence security services from FortiGuard labs to deliver top-rated protection and high performance, including encrypted traffic.
In increasing the maximum VDOM count for mid-range FortiGate 200-400 and 500-900 series, and the FortiOS versions are v7.2.x, v7.4.x, or v7.6.0, the below command is not available.
execute upd-vd-license
Aside from manually uploading the updated entitlement file, it is required to run execute upd-vd-license for the update to take effect.
This is due to bug ID 1029843: increase VDOM limit on mid-range FortiGate models. This bug is resolved in the v7.6.1GA version.
