BlackBerry Enterprise Server for IBM Lotus Domino Upgrade Guide
In a mixed-version environment that includes BlackBerry Enterprise Server Version 2.2 and BlackBerry Enterprise
Server Version 4.0 or later, you require two BlackBerry Mobile Data Service push servers.
BlackBerry Enterprise Server Version 2.2 uses the BlackBerry Directory database to store the BlackBerry Mobile
Data Service configuration and access details. When you upgrade to BlackBerry Enterprise Server Version 4.0 or
later, that information migrates to the BlackBerry Configuration Database, and the BlackBerry Directory database
is no longer used by the BlackBerry Enterprise Server.
You cannot push application data to user accounts on BlackBerry Enterprise Server Version 2.2 from a BlackBerry
Mobile Data Service that uses the BlackBerry Configuration Database, and you cannot push application data to
user accounts on BlackBerry Enterprise Server Version 4.0 or later from a BlackBerry Mobile Data Service that
does not use the BlackBerry Configuration Database.
In a mixed-version environment that includes BlackBerry Enterprise Server Version 4.1 and earlier, the BlackBerry
MDS Connection Service central push server must be Version 4.1.
BlackBerry Enterprise Server Version 4.1.2 or later considerations
In a mixed-version environment that includes BlackBerry components at Version 4.1.2 or later, the BlackBerry
Manager must not be at a higher version than the BlackBerry Configuration Database.
