Upgrade Guide Upgrading the BlackBerry Enterprise Server software in phases Upgrading the BlackBerry Enterprise Server 10 software in phases If you use the phased upgrade process, you can maintain previous versions of the BlackBerry® Enterprise Server software, install additional BlackBerry Enterprise Server instances over time, and move user accounts to the latest BlackBerry Enterprise Server versions. When you use the phased upgrade process, all BlackBerry devices receive new IT policies. Devices that are running BlackBerry® Device Software version 4.0 or later receive new service books and wireless data synchronization occurs. When you move user accounts, the BlackBerry Messaging Agent copies the BlackBerry state databases to the new BlackBerry Enterprise Server. The BlackBerry Configuration Database and all BlackBerry Administration Service instances in the BlackBerry 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 phased upgrade process include: • You can move user accounts to the new BlackBerry Enterprise Server instances gradually to limit the number of service books and IT policies that the BlackBerry Policy Service sends to devices at the same time. • You can monitor system performance while you add user accounts. • You can change your organization's environment during the upgrade process by changing which user accounts you associate with each BlackBerry Enterprise Server instance. Disadvantages of this upgrade process include: • You require extra computers. • You require additional SRP credentials. • If you move user accounts from one BlackBerry Configuration Database to another, you lose the device options that you backed up in the BlackBerry Configuration Database. • You cannot use some new features (for example, one-to-many relationships between a BlackBerry MDS Connection Service or BlackBerry Collaboration Service and multiple BlackBerry Enterprise Server instances) in the BlackBerry Enterprise Server until all BlackBerry Enterprise Server components are the same version.

Upgrading the BlackBerry Enterprise Server
software in phases
10
If you use the phased upgrade process, you can maintain previous versions of the BlackBerry® Enterprise Server
software, install additional BlackBerry Enterprise Server instances over time, and move user accounts to the latest
BlackBerry Enterprise Server versions.
When you use the phased upgrade process, all BlackBerry devices receive new IT policies. Devices that are running
BlackBerry® Device Software version 4.0 or later receive new service books and wireless data synchronization occurs.
When you move user accounts, the BlackBerry Messaging Agent copies the BlackBerry state databases to the new
BlackBerry Enterprise Server.
The BlackBerry Configuration Database and all BlackBerry Administration Service instances in the BlackBerry 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 phased upgrade process include:
•
You can move user accounts to the new BlackBerry Enterprise Server instances gradually to limit the number of
service books and IT policies that the BlackBerry Policy Service sends to devices at the same time.
•
You can monitor system performance while you add user accounts.
•
You can change your organization's environment during the upgrade process by changing which user accounts
you associate with each BlackBerry Enterprise Server instance.
Disadvantages of this upgrade process include:
•
You require extra computers.
•
You require additional SRP credentials.
•
If you move user accounts from one BlackBerry Configuration Database to another, you lose the device options
that you backed up in the BlackBerry Configuration Database.
•
You cannot use some new features (for example, one-to-many relationships between a BlackBerry MDS
Connection Service or BlackBerry Collaboration Service and multiple BlackBerry Enterprise Server instances) in
the BlackBerry Enterprise Server until all BlackBerry Enterprise Server components are the same version.
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.
