BlackBerry Enterprise Server for Microsoft Exchange Upgrade Guide
Changes to the BlackBerry Enterprise Server Version 3.6 environment
When you upgrade from BlackBerry Enterprise Server Version 3.6, the following changes occur:
• updates to the BlackBerry Enterprise Server software
• consolidation of BlackBerry Enterprise Server instances
• creation of a new schema for the BlackBerry Configuration Database
• migration of user accounts to the new schema
You can preview the user account migration into the BlackBerry Configuration Database to identify any issues that
might occur (for example, identifying inactive user accounts that you cannot migrate) and to estimate the time
that it should take to migrate user accounts during the upgrade process.
Changes to the BlackBerry Enterprise Server Version 4.0 environment
When you upgrade from BlackBerry Enterprise Server Version 4.0, the following changes occur:
• updates to the BlackBerry Enterprise Server software, including any BlackBerry components that you installed
separately (for example, the BlackBerry Manager)
• upgrades to the schema of the BlackBerry Configuration Database
Before you upgrade to BlackBerry Enterprise Server Version 4.1.4, make sure that all BlackBerry Enterprise Servers
in your environment that share a BlackBerry Configuration Database are Version 4.0.3 or higher. Certain
components in earlier versions of the BlackBerry Enterprise Server are not optimized for use with the BlackBerry
Enterprise Server Version 4.1.4.
