Fail over device service manually

By default, the primary instance is configured to fail over automatically if any of the health parameters above the failover threshold become unhealthy. If the primary instance of the BlackBerry Enterprise Service 10 components is not running as expected, or if you want to perform maintenance activities on the primary instance, you can manually fail over device service to the standby instance.
Before you begin: Verify that the standby instance is running.
  1. In the BlackBerry Administration Service, on the Servers and components menu, expand High availability > Highly available instances.
  2. Click the appropriate high availability pair.
  3. In the High availability actions list, click Manual failover.
  4. In the Select Standby Instance section, select the standby instance that you want device service to fail over to.
  5. Click Yes – Failover to standby instance.
