Upgrade Planning Guide	Upgrade implications for a BlackBerry Enterprise Server connection to a remote BlackBerry MDS
	Connection Service or BlackBerry Collaboration Service

•The latest BlackBerry MDS Connection Service version might require more memory than previous versions because you can configure it to connect to multiple BlackBerry Enterprise Server instances. The latest version of the BlackBerry MDS Connection Service central push server caches all user data from all BlackBerry Enterprise Server instances.

Before you can upgrade the BlackBerry MDS Connection Service, you must upgrade a BlackBerry Configuration Database and a BlackBerry Enterprise Server instance. You must also install a BlackBerry Administration Service.

The upgrade process removes the SNMP monitoring of the server-level events associated with the BlackBerry MDS Connection Service. To monitor the server-level events after the upgrade process completes, you can use the BlackBerry® Monitoring Service.

After you upgrade the BlackBerry MDS Connection Service, you must update your organization's push applications to use the new x-rim-push-gateways header. In earlier versions, when the BlackBerry MDS Connection Service received the UserAgent:MDSRuntime header from a push application, the BlackBerry MDS Connection Service sent the host:port of the central push server in the http_via header. The latest BlackBerry MDS Connection Service version does not send the http_via header.

Upgrade implications for a BlackBerry Enterprise Server connection to a remote BlackBerry MDS Connection Service or BlackBerry Collaboration Service

When you upgrade a BlackBerry® Enterprise Server, the upgrade process maintains the existing connections to the BlackBerry MDS Connection Service instances or BlackBerry Collaboration Service instances. If the BlackBerry Enterprise Server connects to BlackBerry MDS Connection Service instances or BlackBerry Collaboration Service instances that you installed on remote computers, and during the upgrade process you install a BlackBerry MDS Connection Service instance or BlackBerry Collaboration Service instance with the BlackBerry Enterprise Server, the setup application does not connect the BlackBerry Enterprise Server to the BlackBerry MDS Connection Service instance or BlackBerry Collaboration Service instance that you install on the same computer.

You can use the BlackBerry Administration Service to configure the BlackBerry Enterprise Server to connect to the local BlackBerry MDS Connection Service or BlackBerry Collaboration Service instance after the upgrade process completes.

Upgrade implications for the BlackBerry Monitoring Service

To monitor the latest BlackBerry® Enterprise Server version, you must install the latest BlackBerry® Monitoring Service version.

BlackBerry Monitoring Service 5.0 and later does not support monitoring BlackBerry Enterprise Server 4.1 instances. If your organization's environment includes instances of BlackBerry Enterprise Server 4.1 SP7, you can use BlackBerry Monitoring Service 4.1 SP7 to monitor BlackBerry Enterprise Server 4.1 instances. You must install the latest BlackBerry Monitoring Service version on a computer that does not host BlackBerry Monitoring Service 4.1 SP7 and create a new BlackBerry Monitoring Service database to monitor the latest BlackBerry Enterprise Server version.
