Installation guide

Planning a BlackBerry

Enterprise Server

If your organization's environment includes only one BlackBerry Enterprise Server that is version 5.0 SP2 or later, you can

upgrade the

BlackBerry Enterprise Server to the latest version by overwriting it or by installing it on a different computer

and moving the user data to the upgraded BlackBerry Enterprise Server.

If your organization's environment includes more than one BlackBerry Enterprise Server that is version 5.0 SP2 or later, you

can upgrade each

BlackBerry Enterprise Server instance to the latest version in phases to reduce the risk to your

organization's environment and minimize the number of users that the upgrade might affect at the same time.

If mirroring is enabled in your organization's environment, you must run on the primary database to perform an upgrade.

Upgrades are not supported when running in a mirrored failover state.

For information about upgrading more than one BlackBerry Enterprise Server, see the BlackBerry Enterprise Server

Upgrade Planning Guide.
