Prerequisites: Installing a standby instance of the core components
- Install a primary instance of the core components. Verify whether this instance is assigned the device management role for Android devices and iOS devices. By default, the setup application assigns this role to the first instance of the core components that you install in the domain, or to the first instance that you upgrade.
- Choose a different computer to host the standby instance of the core components. Verify that this computer meets the appropriate system requirements.
- When you install the standby instance, use the same service account that you used to install the primary instance, or a service account with the same permissions.
- It is a best practice to upgrade all BlackBerry 10 devices in your organization's environment to BlackBerry 10 OS version 10.1 or later. If device service fails over to the
standby instance, you can continue to use the consoles to manage BlackBerry devices only if the devices use BlackBerry 10 OS version 10.1 or later.If the devices use an earlier version of the BlackBerry 10 OS or the BlackBerry PlayBook OS, the devices cannot connect to the Enterprise Management Web Service of the new primary instance (formerly the standby instance). As a result, you cannot manage the devices from the consoles until you perform one of the following actions:
- Manually fail over device service back to the initial primary instance.
- Move the user account and any associated devices to another high availability pair in the domain.
- Activate the devices again.
