BlackBerry Enterprise Server 4.1 for MDS Applications, 20u PRD-10459-034 User Manual

Upgrading the BlackBerry Enterprise Server by using a new

computer

5

The cutover upgrade process installs the BlackBerry® Enterprise Server on a new computer and moves user accounts and server
information from the old BlackBerry Enterprise Server to the new one.

Advantages

Disadvantages

•

You can move user accounts back to the old BlackBerry
Enterprise Server if you encounter any problems with the
new one.

•

You can use new server hardware and start with a clean
environment.

•

Users experience minimal service interruptions because
user accounts remain active on the old BlackBerry
Enterprise Server until you start the new one.

•

You require one extra computer.

•

If you upgrade from a version earlier than BlackBerry
Enterprise Server Version 4.0, the BlackBerry Enterprise
Server takes longer to start than it did previously because
it sends new service books to all of the BlackBerry devices
that are capable of wireless data synchronization.

This upgrade process uses the same SRP credentials on both the old and the new BlackBerry Enterprise Server instances.

When you use the cutover process, the following events occur:

•

BlackBerry devices that are running BlackBerry® Device Software Version 4.0 or later receive new service books, and wireless
data synchronization occurs.

•

All BlackBerry devices receive new IT policies.
