HP HPE VAN SDN Controller 2.7, Administrator'S Manual, Page: 94 / 231

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, no special effort is required to preserve the licenses. Note that the license
transfer mechanism is only required when you want to switch the controller currently running
hardware. You must install the 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:
•
Deactivate all licenses, as described in “Deactivating licenses to prepare for transfer”
(page 94) .
•
Obtain an Install ID for each destination controller, as described in “Identifying the Install ID
displayed in the controller UI” (page 87) .
Deactivating licenses to prepare for transfer
When you deactivate a license to prepare for transfer, 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 use curl commands and the REST APIs to complete this task, see “curl commands” (page 170) .
To deactivate a license using the controller UI, use the following procedure.
1.
In the controller UI, from the navigation menu, select Licenses .
2. Select the license to deactivate to prepare for transfer.
