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.

You can consider upgrading a BlackBerry MDS Integration Service instance to the latest version if one of the following conditions apply:
  • 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 your organization plans to configure BlackBerry MDS Integration Service high availability, you must upgrade the BlackBerry MDS Integration Service version 4.1 instance as the first instance in the BlackBerry MDS Integration Service pool. You must use the FQDN of the computer that hosts the BlackBerry MDS Integration Service instance as the virtual name of the BlackBerry MDS Integration Service pool.

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.

Install a BlackBerry MDS Integration Service pool in an upgraded environment

When you install new BlackBerry® MDS Integration Service instances in an upgraded environment instead of upgrading existing BlackBerry MDS Integration Service instances, you lose backend notification subscriptions. BlackBerry devices that run BlackBerry® MDS Runtime Application versions earlier than version 4.5 remove the applications.
  1. Install all BlackBerry MDS Integration Service instances in the pool.
  2. Publish all existing BlackBerry MDS Runtime Applications.
  3. Install all BlackBerry MDS Runtime Applications on a test BlackBerry device.
  4. To migrate users from BlackBerry MDS Integration Service version 4.1 to the new BlackBerry MDS Integration Service pool, in the BlackBerry Administration Service, update the BlackBerry Enterprise Server to associate with the new BlackBerry MDS Integration Service pool.
After you finish:
  • Configure backend notification subscriptions.
  • Resend applications to BlackBerry devices that run BlackBerry MDS Runtime Application versions earlier than version 4.5.
  • For more information, see the BlackBerry Enterprise Server Installation Guide.
