Upgrade implications for the BlackBerry MDS Connection Service
- 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.
- 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.
- You cannot use a proxy server to send and receive data between the BlackBerry MDS Connection Service and BlackBerry MDS Integration Service instance. Instead you must configure a direct HTTP connection and the BlackBerry MDS Connection Service proxy rules with the correct host name to use a direct connection to the BlackBerry MDS Integration Service.
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.
