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.
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:
Log on to the My Networking portal at http://www.hp.com/networking/mynetworking.
The transfer license screen displays a list of associated licenses, as shown in Figure 37.
The license details screen appears, as shown in Figure 38.
The target install ID screen appears (Figure 39).
In the screen in Figure 39, do the following:
In the Target Install ID field, enter the Install ID of the controller to which you want to transfer the license.
In each Uninstall field, enter a license uninstall key. (For more on acquiring uninstall keys, see Section .)
NOTE: In order for the transfer process to succeed, you must enter an Uninstall value for every registered license.
Click on the Transfer button in the lower-right corner of the screen.
New license registration information displays on the license transfer confirmation screen and license details screen, as shown in Figure 40.
The license screen displays the status of the original licenses as Transferred, and the new Install IDs as Active, as shown in Figure 41.
To register the transferred licenses on the new controller, see “Activating a license on the controller”.
