Upgrade Guide Planning a BlackBerry Enterprise Server upgrade Planning a BlackBerry Enterprise Server 3 upgrade If your organization's environment includes only one BlackBerry® Enterprise Server that is version 4.1 SP7 or later, you can upgrade the BlackBerry Enterprise Serverto 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 4.1 SP7 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. For information about upgrading more than one BlackBerry Enterprise Server, see the BlackBerry Enterprise Server Upgrade Planning Guide. Supported BlackBerry Enterprise Server versions that you can upgrade You can upgrade the following BlackBerry® Enterprise Server versions to the latest version: • BlackBerry Enterprise Server 5.0 or later • BlackBerry Enterprise Server 4.1 SP7 If your organization has a BlackBerry Enterprise Server version that is not listed, you must first upgrade to one of the BlackBerry Enterprise Server versions in the list above before you can upgrade to the latest version. Replacing the BlackBerry Manager with the BlackBerry Administration Service In BlackBerry® Enterprise Server versions later than version 4.1, the BlackBerry Administration Service replaces the BlackBerry Manager as the BlackBerry Enterprise Server component that you use to manage the BlackBerry Enterprise Server and BlackBerry device users. During the BlackBerry Enterprise Server upgrade process, the setup application removes the BlackBerry Manager. If you installed a standalone BlackBerry Manager, you can remove the BlackBerry Manager after you install the BlackBerry Administration Service. After the BlackBerry Enterprise Server upgrade process completes, you must create administrator accounts for the administrators in your organization and provide the administrators with new login information and the BlackBerry Administration Service web address. If you try to run the BlackBerry Manager, it displays the "DB version greater than maximum currently supported" message and closes. 7
