7: Upgrading the BlackBerry Enterprise Server using a phased process
Sample unsupported mixed-version environment
New features in the BlackBerry Enterprise Server Version 4.1.2 or later—for example, one-to-many relationships
between a BlackBerry MDS Connection Service or a BlackBerry Collaboration Service and multiple BlackBerry
Enterprise Servers—require that all BlackBerry components be at Version 4.1.2 or later. If you are administering a
BlackBerry Enterprise Server Version 4.1.0 or Version 4.1.1 with a BlackBerry Manager Version 4.1.2 or later, these
new features are hidden.
Proxy settings
A BlackBerry Manager Version 4.1.2 or later cannot change proxy settings on a BlackBerry MDS Connection
Service at Version 4.1.0 or Version 4.1.1.
You must re-type the BlackBerry MDS Services proxy settings created on Version 4.1.0 or Version 4.1.1 in the
BlackBerry Manager after you upgrade to Version 4.1.2 or later.
Example 1: Upgrade BlackBerry Enterprise Servers at Version
4.0.3 using a phased process
This example shows how to upgrade a BlackBerry Domain of BlackBerry Enterprise Servers at Version 4.0.3. You
create one new BlackBerry Enterprise Server Version 4.1.4 and use this as the first destination server in a series of
user moves and in-place upgrades.
