Supported upgrade environments
When you upgrade to the latest version of BlackBerry UEM, you upgrade the management console and the database.
The following are the supported upgrade paths:
- You can use the setup application to upgrade from up to two previous versions of UEM. For example, if you have UEM version 12.18, and you want to upgrade to the latest version, you must first upgrade all instances to UEM version 12.20, then upgrade all instances to UEM version 12.22, and continue upgrading in this way until you reach the latest version. As you follow this upgrade path, only the major release version matters (for example, 12.20.x, 12.22.x); you can upgrade up through maintenance release (MR) or quick fix (QF) versions, as long as you meet the major version requirement.
- When you complete the upgrade path, use the latest available version of UEM, including the latest MR or QF release, if available.
- You can install UEM and migrate policy sets, connectivity profiles, app groups, and app usage (for certificates).
If you are upgrading an environment that has activated BlackBerry Dynamics applications on devices, connections to the application servers, including the mail server, will continue to supported. For example, BlackBerry Work will continue to receive email during the upgrade. BlackBerry Dynamics applications cannot be activated during the upgrade. All servers in the environment must be upgraded before any BlackBerry Dynamics applications can be activated. Upgrade all servers in the environment within 24 hours of the first server upgrade.
