The latest BlackBerry® Enterprise Server version contains new features and components (for example, high availability and a new administrative client named the BlackBerry Administration Service) that impact how you can upgrade an existing BlackBerry Enterprise Server environment. To upgrade your organization's environment to the latest BlackBerry Enterprise Server verson, you must determine how you can implement the new components and features in the current BlackBerry Enterprise Server environment, what changes to the hardware and BlackBerry Enterprise Server architecture are required, and which upgrade process is most appropriate for your organization's environment.
You can consider the following information to help you determine which upgrade process you can use in your organization's environment:
•whether you want to upgrade the BlackBerry Enterprise Server environment without modifying the hardware or BlackBerry Enterprise Server architecture
•whether the current BlackBerry Enterprise Server environment supports the new BlackBerry Enterprise Server components and features
•which changes you might want to implement in the BlackBerry Enterprise Server environment during the upgrade process
For system requirements or supported upgrade versions, see the BlackBerry Enterprise Server Upgrade Guide.
Supported BlackBerry Enterprise Server versions that you can upgrade
You can upgrade the following BlackBerry® Enterprise Server versions to the latest version:
•BlackBerry Enterprise Server 5.0 or later
•BlackBerry Enterprise Server 4.1 SP7
If your organization has a BlackBerry Enterprise Server version that is not listed, you must first upgrade to one of the BlackBerry Enterprise Server versions in the list above before you can upgrade to the latest version.
Deployment implications of upgrading a BlackBerry Enterprise Server environment
How you deploy a BlackBerry® Enterprise Server environment determines how you can configure the functionality that is available for each BlackBerry Enterprise Server instance and BlackBerry device user. The BlackBerry Enterprise Server architecture must include at least one BlackBerry Enterprise Server instance and one BlackBerry Configuration Database. If you install additional BlackBerry Enterprise Server instances that use the same BlackBerry Configuration Database, you deploy a BlackBerry Domain.
If you deploy more than one BlackBerry Domain in your organization's environment, the BlackBerry Enterprise Server instances in one BlackBerry Domain cannot communicate with BlackBerry Enterprise Server instances in another BlackBerry Domain. Each BlackBerry Domain must use its own administrative client.
