Transferring feature licenses on BigIP

In v10 you can enable and disable different modules (under System > Resource Provisioning). It is my guess that you would need to disable the module and then probably perform a Re-Activate (under System > License) to clear the license from a device.

 

 

But as hoolio stated, these license are tied specifically to the device so you would still need to work with an F5 Sales Person (if not open up a case with F5) to either get the license freed up, or another license issued to you.
