Upgrade a domain that consists of multiple instances of BlackBerry UEM

If the recommended upgrade path is to upgrade UEM versions in stages, then you must upgrade all instances to the first stage, restart them, and upgrade them all to the second stage. For example, if you are running UEM version 12.19, you must upgrade all instances by two UEM versions at a time to the latest UEM version.

If you’re upgrading your environment in stages, test your environment after each stage of the upgrade to make sure everything is working as expected. If it is not, resolve any issues before proceeding to the next stage of the upgrade.

  1. Upgrade one UEM core instance.
    The setup application also backs up and upgrades the UEM database. After the upgrade, the UEM instance starts automatically.
    When you upgrade a core instance, you must use an upgraded management console instance to connect to that core and manage the domain.
  2. Upgrade the other UEM core or management console instances. You can upgrade these remaining UEM instances more than one at a time.
  3. Upgrade any BlackBerry Connectivity Node-only instances (that contain only the device connectivity components) last. You can upgrade more than one BlackBerry Connectivity Node-only instance at a time.
