Renewing a License Key

License keys are often valid only for a certain period of time.

To upgrade or renew a license key, you can do one of the following:

  • Email Sales.

  • Email Support.

  • Call your sales representative.

To install a new license key, replace the license key on each member host and restart each one at a time. If you want to temporarily add a new license key to a running cluster, you can use the REST API.

If your license is expired on a running cluster or Management Center, do not restart the host device. Reach out to Hazelcast Support to resolve any issues with an expired license.
