4.6.1 Transferring licenses
You can transfer a license from one controller to another. To do so, you must first uninstall all
licenses from the controller.
NOTE: Keeping a license on one controller while transferring one or more other licenses from
the same controller to another controller is not permitted.
When upgrading to version 2.3, no special effort is required to preserve the licenses. Note that
the license transfer mechanism is only required when you want to switch the SDN Controller currently
running hardware. You must install the SDN Controller on the new hardware and transfer the
licenses to that new hardware before retiring the old hardware.
Before you transfer licenses
Before you transfer licenses, you must first:
• Uninstall all licenses, as described in “Uninstalling licenses to prepare for transfer” (page 60).
• Obtain an Install ID for each destination controller, as described in “Identifying the install ID”
(page 53).
