Install an additional
BlackBerry UEM
 instance

You can install additional
BlackBerry UEM
 instances to create a high availability domain. Verify that the computer satisfies the system requirements for installing a
UEM
 instance, and complete the necessary pre-installation and post-installation tasks.
When you install additional
UEM
 instances:
  • Install each instance on a separate computer.
  • You must install the same version as the original
    UEM
     instance. If you install an earlier version, the
    UEM Core
     on the new server cannot be accessed.
  • In the setup application, on the
    Setup type
     screen, select
    Use an existing BlackBerry UEM database
    .
  • On the
    Database information
     screen, specify the information for the
    UEM
     database that you created when you installed the original
    UEM
     instance.
After you install an additional
UEM
 instance and complete the necessary post-installation tasks, active-active high availability is available in the domain. User and device data is load-balanced across the
UEM
 instances.
