• You can use the BlackBerry Administration Service to view BlackBerry Attachment Service version 4.1 settings
for the BlackBerry Messaging Agent, BlackBerry MDS Connection Service, and BlackBerry Collaboration Service,
but you cannot change the settings.
• You can continue to configure BlackBerry Attachment Service version 4.1 using the BlackBerry Configuration
Panel.
During the BlackBerry Attachment Service upgrade process, the BlackBerry Attachment Service settings that are
stored in the Windows® registry move to the BlackBerry Configuration Database.
Before you can upgrade the BlackBerry Attachment Service, you must upgrade the BlackBerry Configuration Database
and a BlackBerry Enterprise Server instance. You must also install the BlackBerry Administration Service.
Upgrade implications for the BlackBerry Collaboration
Service
Before you upgrade to the latest version of the BlackBerry® Collaboration Service or BlackBerry® Enterprise Server,
consider the following information:
• You can run the latest BlackBerry Collaboration Service version with BlackBerry Enterprise Server 5.0 or later.
• You can run BlackBerry Collaboration Service 4.1 SP7 or later with the latest BlackBerry Enterprise Server version.
If you installed the BlackBerry Collaboration Service for use with Windows® Messenger, you must upgrade Windows
Messenger to Microsoft® Office Live Communications Server 2005 or later. The latest BlackBerry Collaboration Service
version does not support Windows Messenger.
Before you can upgrade the BlackBerry Collaboration Service, you must upgrade the BlackBerry Configuration
Database and a BlackBerry Enterprise Server instance. You must also install the BlackBerry Administration Service.
Upgrade implications for the BlackBerry MDS Connection
Service
You can run BlackBerry® MDS Connection Service 4.1 SP7 or later with the latest BlackBerry® Enterprise Server
version. Consider the following information:
• The latest BlackBerry Enterprise Server version does not support versions of the BlackBerry MDS Connection
Service central push servers that are earlier than version 5.0. You must upgrade all BlackBerry MDS Connection
Service central push servers that the latest BlackBerry Enterprise Server version uses to version 5.0 or later.
• If you assigned the software configuration for a push application to a group, when you upgrade the BlackBerry
Configuration Database to the latest version, the upgrade process does not migrate the group information. If a
BlackBerry MDS Connection Service version 4.1 instance requests a push to a group that no longer exists, the
push fails and an error message is written to the log file, indicating that the group does not exist.
• The BlackBerry Administration Service permits you to view the BlackBerry MDS Connection Service version 4.1
settings, but it does not permit you to change the settings.
