Upgrading the BlackBerry Enterprise Server using the cutover upgrade process and upgrade the existing BlackBerry Configuration Database
You can use the cutover upgrade process to install a BlackBerry® Enterprise Server on a new computer and move user accounts and server information from a previous BlackBerry Enterprise Server to the new one.
When you use the cutover upgrade process, all BlackBerry devices receive new IT policies. Devices that are running BlackBerry® Device Software version 4.1 or later receive new service books and data synchronization occurs over the wireless network.
The BlackBerry Configuration Database and all BlackBerry Administration Service instances in the BlackBerry Domain must be the same version. Before you upgrade the BlackBerry Configuration Database, you must stop the BlackBerry Administration Service services that run on all other computers in the BlackBerry Domain until you upgrade the computers.
- You can move user accounts back to the previous BlackBerry Enterprise Server if you experience issues with the new one.
- You can upgrade server hardware.
- Users experience minimal service interruptions because user accounts remain active on the previous BlackBerry Enterprise Server until you start the new one.
