Planning a BlackBerry Enterprise Server Express upgrade

If your organization's environment includes only one BlackBerry® Enterprise Server Express, you can upgrade the BlackBerry Enterprise Server Express to the latest version by overwriting it or by installing the BlackBerry Enterprise Server Express on a different computer and moving the user data to the upgraded BlackBerry Enterprise Server Express.

If your organization's environment includes more than one BlackBerry Enterprise Server Express, you can upgrade each BlackBerry Enterprise Server Express instance to the latest version in phases to reduce the risk to your organization's environment and minimize the number of users that are affected at the same time.
