Which must be sent to the license server to generate a new license?

A system's dossier is a unique identifier that contains specific hardware and software configuration information of the device, often including its serial number or MAC address. This dossier is crucial for the license server to generate a license key that is specifically tied to and valid for that particular physical or virtual machine.

A system's host name is a configurable label and not a unique, immutable identifier required for license generation.

The base license is an existing license for the system, not a piece of information sent to generate a new license, although upgrades might reference it.

While a purchase order number is used for procurement, it is not a technical identifier sent to the license server to generate a system-specific license key.
