Upgrading the BlackBerry Enterprise Server
using a phased process
Phased upgrades
You can upgrade your BlackBerry Enterprise Servers to Version 4.1.3 in phases using a combination of the in-place
and cutover processes while maintaining BlackBerry Enterprise Servers at versions earlier than 4.1.3.When you
upgrade your BlackBerry environment gradually, you must use different administrative tools to manage the
different versions of the BlackBerry Enterprise Server. When you upgrade to BlackBerry Enterprise Server Version
4.1.4 and your environment contains BlackBerry components at Version 4.1.1 and earlier, you must verify which
BlackBerry component version combinations are supported. You must also consider how changes to the
configuration and user access information impact existing versions of the BlackBerry Mobile Data Service
(BlackBerry MDS Connection Service).
Managing a mixed-version environment
The administrative tools that you use to manage a mixed-version environment depend on the versions of the
BlackBerry Enterprise Server that you continue to operate.
Until your BlackBerry Enterprise Servers at Version 2.2 are upgraded to use the BlackBerry Configuration
Database, and the server and user configuration information become accessible to the BlackBerry Manager, you
must continue to use the BlackBerry Server Manager as the administrative tool.
You can create a BlackBerry Domain—multiple BlackBerry Enterprise Servers sharing a single BlackBerry
Configuration Database—with BlackBerry Enterprise Servers Version 4.0 and Version 4.1 so that you can move
user accounts easily and limit their service interruption.
After you upgrade the BlackBerry Configuration Database to Version 4.1, you must administer all BlackBerry
Enterprise Servers in that BlackBerry Domain using BlackBerry Manager Version 4.1.
BlackBerry Mobile Data Service (BlackBerry MDS Connection Service)
considerations
After you upgrade the BlackBerry Mobile Data Service to Version 4.1 or later, the service name becomes the
BlackBerry MDS Connection Service.
