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.
- Install the latest BlackBerry Enterprise Server version with the BlackBerry Administration Service on a separate computer.
- If you create a new BlackBerry Configuration Database, create roles, administrator accounts, groups, IT policies, and software configurations for your organization's environment.
- If you upgrade an existing BlackBerry Configuration Database, remove BlackBerry Manager instances from your organization's environment.
- Move user accounts to the upgraded BlackBerry Enterprise Server by performing one of the following actions:
- Upgrade instances of the central push server for the BlackBerry MDS Connection Service.
- 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.
- 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.
