Rolling upgrade to a newer version

Follow these tasks to upgrade your Operational Decision Manager to a recent version.

These tasks are for Operational Decision Manager 8.9.2 or a newer version. A rolling upgrade to 8.10.3 or newer is not supported from versions earlier than 8.9.2. To do so, you must shut down your system during the upgrade. For more information, see Migration scenarios.

When you upgrade from 8.9.2 or a newer version to 8.10.3 or newer, in-place upgrade of the Rule Execution Server and Decision Warehouse databases is not necessary because the schemas of these databases are compatible between the versions.

The testing and simulation features are not part of the rolling upgrade. You must stop using these features before the rolling upgrade begins, and you cannot use them during the rolling upgrade to prevent two versions of the Scenario Service Provider from existing on the same node. You must deploy the testing and simulation archive after the rolling upgrade.

Operational Decision Manager 8.10.x does not support Java 7. You must upgrade to Java 8 to work in 8.10.x.
