Deregistering a license from host ID

As of Niagara 4.15, you can deregister a Niagara license from a host ID by connecting Workbench to the Niagara platform or by using the NRE command. You can perform the deregistration of a license directly from your station. Use the following steps to deregister a host ID.

  • You have created a Niagara Central account (https://www.niagara-community.com) and you have access to Niagara Licensing.

  • You are a Niagara Licensing portal user with Write/WriteX permissions on Subscription License.

Using Workbench

  1. Open Workbench and make a platform connection to the Niagara instance.
  2. In the Nav tree, double-click on the License Manager.


  3. Verify that the Niagara instance is registered to a host ID and the Register button is disabled.
  4. To deregister the license, click Deregister.
    The Deregister Host ID window opens to ask you if you want to proceed with the deregistration.

  5. Click OK to continue.
  6. Upon successful deregistration, a dialog window opens confirming that the host ID is deregistered, along with the unbound license key. You can use the unbound licensing key to register a new host ID.
    Note: Retain a copy of the licensing key. To register a new device to the subscription, you can use the unbound license key. The license key has been exported to the remote host's security/subscription/deregistration folder.

Using NRE command

  1. Open the Niagara console command line for the Niagara instance to be deregistered. On a Linux Niagara instance, open the shell application.


  2. Check if the host ID is currently bound by running the NRE command: nre -checksub and registered with the entitlement system.


  3. To deregister the license from the host ID, run the command nre -deregister.
    Upon successful deregistration, the console will display a message confirming that the device is deregistered. The original subscription key will also be displayed and can be bound to another host ID.
