About Upgrading TimesTen Classic Databases

The TimesTen Operator provides support for upgrading TimesTen Classic databases that are deployed in your Kubernetes namespace. The support is applicable to both replicated and non-replicated configurations. For each configuration, the TimesTen Operator supports an automated and a manual image upgrade strategy. The TimesTen Operator determines the upgrade strategy from the .spec.ttspec.imageUpgradeStrategy datum. If the value is Auto (or not specified), the upgrade process is automated. If the value is Manual, the upgrade process is manual. You have the option of specifying the .spec.ttspec.imageUpgradeStrategy datum when you define the attributes for your TimesTenClassic object. See About Defining TimesTenClassic Objects.

The upgrade process is dependent on the configuration and the image upgrade strategy. The upgrade processes are discussed in the following sections:
