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”.
Obtain an Install ID for each destination controller, as described in “Identifying the install ID”.

Uninstalling licenses to prepare for transfer

When you deactivate a license, the controller generates an Uninstall Key for that license, which you will need when you transfer the license. Be prepared to record the Uninstall Key for each license you deactivate. The Uninstall Key is a long text string. For example:

AE2RCLT7CJMDI-MAGAQHS2NBTOB-6VM4QKEQ4HAEZ-3AY4QELRPG4AA-3EMHQELRPGAYQ

To uninstall a license using the controller UI, use the following procedure.

From the navigation menu, select Licenses.
Select the license to uninstall.
Click Deactivate.
Click OK when the deactivation prompt appears:
Record the Uninstall key appearing in the Uninstall Key field for that license.
Repeat the preceding steps for each of the remaining licenses on the controller.

Transferring licenses

After you have uninstalled all of the licenses for a controller, you can transfer them to another controller.
