Technical Tip: How to deregister FortiGate using FortiCloud

Note:

The process detailed below removes existing firewall licenses and removes the serial number from managed assets. It should only be used when decommissioning a device before disposal.

To deregister from FortiCloud Portal:

Visit https://support.fortinet.com portal and select Products -> Product List:

Select Product Serial Number and decommission this unit:

Go to More Views -> Decommissioned Products -> Deregister:

Note:

When decommissioning a virtual machine or a device registered under three years, the following error will be displayed:

If a physical unit has been registered for fewer than three years, reach out to Customer Support to decommission the device.

See this document:

FortiGate VM cannot be deregistered, only FortiGate hardware devices.
