Upgrading the BlackBerry Enterprise Server software by using the in-place upgrade process
Using the in-place upgrade process, you can upgrade the BlackBerry® Enterprise Server software by replacing the existing version and upgrading the BlackBerry Configuration Database.
You can use the in-place upgrade process if your organization's environment includes a standalone BlackBerry Enterprise Server instance.
When you use the in-place upgrade process, all BlackBerry devices receive new IT policies. BlackBerry devices that are running BlackBerry® Device Software version 4.1 or later receive new service books and data synchronization occurs over the wireless network.
Disadvantages of this upgrade process include:
- After you upgrade the BlackBerry Enterprise Server, you cannot return to an earlier version of the software automatically.
- You must turn off the BlackBerry Enterprise Server during the upgrade process. The interruption to services for BlackBerry devices lasts for as long as it takes the upgrade process to complete.
