or Microsoft SQL Server account that you use to complete the BlackBerry Enterprise Server installation process. If you

want the setup application to install the BlackBerry database notification system, you must assign the Microsoft SQL

Server permission for the database system administrator (also called the sysadmin server role in Microsoft SQL Server

Management Studio) to the Windows account or Microsoft SQL Server account.

Resolving IT policy and application control

policy conflicts in a mixed version

environment

In BlackBerry Enterprise Server versions earlier than version 5.0, the BlackBerry Policy Service queues delivery requests

for IT policies and application control policies and sends them to BlackBerry devices. In BlackBerry Enterprise Server

version 5.0, the BlackBerry Administration Service queues the IT policies and application control policies, and the

BlackBerry Policy Service sends them to BlackBerry devices.

To avoid conflicts between the BlackBerry Policy Service and BlackBerry Administration Service in a mixed version

environment, the setup application tries to turn off application polling by the BlackBerry Policy Service for each BlackBerry

Enterprise Server instance in the BlackBerry Enterprise Server domain before it starts the upgrade process. When the

setup application turns off application polling, it prevents earlier versions of the BlackBerry Policy Service from queuing

delivery requests for IT policies and application control policies.

If the setup application cannot turn off application polling for all BlackBerry Enterprise Server instances (for example, a

computer that hosts one of the

BlackBerry Enterprise Server instances is not running), you must run the

BB50UpgradePrep tool manually before you can upgrade the BlackBerry Enterprise Server.
