Upgrading the number of VM CPUs

FortiDDoS-VM is licensed for either 4, 8, or 16 CPUs. If you start with one license and outgrow it, you can upgrade.

Before you begin:

• You must purchase the new license and copy the license file to your management computer.
• Be aware that you must shut down FortiDDoS and power off the virtual machine to perform the upgrade.

To allocate more vCPUs:

1. In the FortiDDoS web UI, go to System > Status > Dashboard.
2. Upload the new license. For details, see Step 6: Upload the license file.
3. In the System Information widget, click Shut Down.

The virtual appliance will flush its data to its virtual disk, and prepare to be powered off. If you skip this step and immediately power off FortiDDoS-VM, you might lose buffered data.

4. On your management computer, log into the VMware server.
5. In the left pane, click the name of the virtual appliance, such as FortiDDoS-VM-Doc.
6. Click the Getting Started tab.
7. Click Power off the virtual machine.
8. Increase the vCPU allocation. For details, see Configuring the number of virtual CPUs (vCPUs).



9. Power on the virtual appliance again.
