Upgrade multiple BlackBerry Enterprise

Server instances in phases

You can upgrade the BlackBerry Enterprise Server instances in your organization's environment in phases to minimize the

impact on users.

Before you begin: If you want to create a new BlackBerry Configuration Database, instruct users to back up their

BlackBerry devices. Any BlackBerry device options that are stored in the existing BlackBerry Configuration Database are

deleted when you add user accounts to the new BlackBerry Configuration Database.

1. Install the latest BlackBerry Enterprise Server version with the BlackBerry Administration Service on a separate

computer.

2. If you create a new BlackBerry Configuration Database, create roles, administrator accounts, groups, IT policies, and

software configurations for your organization's environment.

3. If you upgrade an existing BlackBerry Configuration Database, remove BlackBerry Manager instances from your

organization's environment.

4. Move user accounts to the upgraded BlackBerry Enterprise Server by performing one of the following actions:

• To upgrade an existing BlackBerry Configuration Database, move user accounts using the BlackBerry

Administration Service.

• To create a new BlackBerry Configuration Database, move user accounts using the BlackBerry Enterprise

Transporter.

5. Upgrade instances of the central push server for the BlackBerry MDS Connection Service.

6. Upgrade the earlier BlackBerry Enterprise Server version using an in-place upgrade process. You can use the

upgraded BlackBerry Enterprise Server instance as the destination for user accounts that you move from earlier

BlackBerry Enterprise Server versions.

7. Move user accounts to the upgraded BlackBerry Enterprise Server instances, and upgrade the old BlackBerry

Enterprise Server instances until all BlackBerry Enterprise Server instances are running the latest software version.

After you finish: To enable BlackBerry device users to access the features that are part of the latest version, upgrade the

BlackBerry Device Software. For more information, see the BlackBerry Device Software Update Guide.
