Upgrading the BlackBerry

Enterprise Server using the

cutover upgrade process and

upgrading 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.

If you upgrade the existing BlackBerry Configuration Database, you can move user accounts from the previous BlackBerry

Enterprise Server to the new one using the BlackBerry Administration Service.

The BlackBerry Configuration Database and all BlackBerry Administration Service instances in the BlackBerry Enterprise

Server 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.

Advantages of the cutover upgrade process include:

• 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.

Disadvantages of this upgrade process include:

• You require an extra computer.

• The BlackBerry Enterprise Server sends new service books to all devices that can synchronize data over the wireless

network.
