You can license a product on a specific machine with either an online or an offline license activation method. You can activate existing licenses with other license types. For example, you can activate a commercial license while a trial license is in effect.
Important: When you have more than one activated license for a specific
product, the most recently activated license is the effective license. However, this
does not apply to emergency grace and trial licenses.
Note: If you move or copy a VM to a different host, it changes the System ID of the VM.
This invalidates the software licenses on that VM and causes licensing errors for
your software.
Grace and trial licenses take effect only if there is no other active license on the machine. A non-expired license takes effect on the machine when the effective license expires. If you reactivate a commercial license that is already on the machine, it becomes the top license. See Changing the top license in the License Inventory table.
