Switch the primary and standby instances
You can switch the primary instance in a high availability pair to a standby instance at any time. For example, you may want to stop device service on the primary instance for a short period of time while you complete maintenance activities. When both instances in a high availability pair are standby instances, device service is not active on either instance. When you complete your maintenance activities, you can choose which standby instance you want to promote to become the primary instance. You need to complete some additional configuration if you choose to promote the original standby instance to become the new primary instance.
- In the BlackBerry Administration Service, on the Servers and components menu, expand High availability > Highly available instances.
- Click the appropriate high availability pair.
- In the High availability actions list, click Change primary instance to standby instance.
- Click Yes – Change instance to standby instance.

- In the High availability actions list, click Change standby instance to primary instance.
