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 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.
Resolve IT policy and application control policy conflicts in a mixed version environment
1. Copy the BlackBerry® Enterprise Server installation media to the computer that hosts a BlackBerry Enterprise Server.
2. Extract the contents to a folder on the computer.
3. In the <extracted_folder>\tools folder, double-click BB50UpgradePrep.exe.
4. Complete the instructions on the screen.
Backing up the BlackBerry Configuration Database
You must back up the BlackBerry® Configuration Database so that you can restore it if the BlackBerry® Enterprise Server upgrade
process does not complete.
If your organization's environment includes Microsoft® SQL Server®, use the backup and restore tools that Microsoft provides
to back up the BlackBerry Configuration Database.
If your organization's environment includes an MSDE 2000 or Microsoft SQL Server Express, you can use the BlackBerry
Configuration Database Backup Tool that is included with the BlackBerry Enterprise Server installation media to back up the
BlackBerry Configuration Database to a file. By default, the backup file is named <database_name> <YYYYMMDDHHMMSS>.bak.
