Upgrading a BlackBerry Domain
5
If you upgrade a BlackBerry® Enterprise Server environment that includes more than one BlackBerry Enterprise Server
instance, you can choose from a variety of upgrade processes, depending on the existing architecture of the
BlackBerry Domain and how you expect the architecture to change as you add BlackBerry device users, install
additional BlackBerry Enterprise Server components and instances, and configure new features.
You can consider the following infrastructure variations as you plan the upgrade process for your organization's
environment.
Variation Description
MSDE or Microsoft® SQL Server®
used to host the BlackBerry
Configuration Database
If your organization's environment includes MSDE, you must upgrade to a
later version of Microsoft SQL Server.
You can upgrade to Microsoft SQL Server Express if your organization's
environment does not include many BlackBerry device users and you do not
plan to add any more.
You can upgrade to Microsoft SQL Server if you expect the number of
BlackBerry device users to increase to more than 500.
You can upgrade the database server that hosts the BlackBerry
Configuration Database before you upgrade the BlackBerry Enterprise
Server.
BlackBerry Configuration Database
installed locally or on a separate
computer
If you expect the number of BlackBerry device users to increase, you might
want to install the BlackBerry Configuration Database on its own computer.
When you install the BlackBerry Configuration Database on its own
computer, you increase the system resources that are available to the
BlackBerry Configuration Database and BlackBerry Enterprise Server, and
make it easier to configure features such as high availability.
network proximity of the BlackBerry
Enterprise Server, BlackBerry
Configuration Database, messaging
servers, and other third-party
systems
If you configure the BlackBerry Enterprise Server, BlackBerry Configuration
Database, messaging servers, and other third-party systems on separate
LANs connected by a WAN, the upgrade process takes longer to complete.
Planning to upgrade the BlackBerry Domain when your
organization's infrastructure is in one location
If you previously installed the BlackBerry® Enterprise Server instances, BlackBerry Configuration Database, and
messaging servers on a single LAN and want to limit the infrastructure changes during the upgrade process, you can
use an in-place upgrade process.
