Upgrade implications for the BlackBerry MDS Integration Service
You can run BlackBerry® MDS Integration Service version 4.1 SP3 or later with the latest BlackBerry® Enterprise Server version. However, the BlackBerry Administration Service cannot manage BlackBerry MDS Integration Service version 4.1 SP3 or later. You must upgrade the BlackBerry MDS Integration Service to the latest version before you can use the BlackBerry Administration Service to change the configuration information for the BlackBerry MDS Integration Service. By default, the upgrade process for the BlackBerry MDS Integration Service does not maintain published BlackBerry® MDS Runtime Applications in the database. For more information, see the BlackBerry Enterprise Server Upgrade Guide.
Before you can upgrade a BlackBerry MDS Integration Service instance, you must upgrade the BlackBerry Configuration Database and install the BlackBerry Administration Service. If your organization's environment includes multiple BlackBerry MDS Integration Service instances, during the first BlackBerry MDS Integration Service upgrade process, the upgrade process also upgrades the existing BlackBerry MDS Integration Service database (by default, mdss).
Configuring BlackBerry MDS Integration Service high availablility during the upgrade process
The setup application creates a separate pool for each BlackBerry® MDS Integration Service instance that you upgrade. You cannot add the upgraded BlackBerry MDS Integration Service instances to a pool so that you can configure high availability. You can configure high availability only for new BlackBerry MDS Integration Service instances that you install.
- Your organization uses the BlackBerry MDS Integration Service as a standalone service and does not have plans to configure BlackBerry MDS Integration Service high availability.
- Your organization plans to configure BlackBerry MDS Integration Service high availability and the existing BlackBerry MDS Integration Service version 4.1 instance is installed on a computer that does not have other software (for example, a database server or third-party applications) installed on it.
If one of the above conditions do not apply, you can consider installing the latest BlackBerry MDS Integration Service version on new computers. When you do so, after installing the BlackBerry MDS Integration Service instances, you must republish the BlackBerry® MDS Runtime Applications.
