FortiGate-7000 Split-Task VDOM mode includes the following limitations:
- You cannot switch an HA cluster between VDOM modes. If you are operating an HA cluster in Multi VDOM mode, you must remove each FortiGate from the cluster, switch the FortiGates to running in Split-Task VDOM mode and then re-configure the cluster. The same applies for switching an HA cluster between Split-Task VDOM mode and Multi VDOM mode.
- Split-Task VDOM mode does not support virtual clustering. FGCP, FGSP, standalone configuration synchronization, and VRRP are supported in Split-Task VDOM mode.
- While switching between Multi VDOM mode and Split-Task VDOM mode, your FortiGate-7000 goes through an intermediate step where it has no VDOMs. The FortiGate-7000 cannot forward data traffic without VDOMs so you must switch to Split-Task VDOM mode to be able to use the FortiGate-7000 to forward data.
- You can't switch to Multi VDOM mode if FortiGate Telemetry is enabled.
