19 Perform Upgrades

The TimesTen Kubernetes Operator provides support for upgrading TimesTen CRDs, the TimesTen Operator, and TimesTen Classic databases to a new patch or patch set.

The TimesTen Operator provides YAML manifest files and Helm charts for upgrading TimesTen CRDs and the TimesTen Operator. You obtain these files from TimesTen container images.

The TimesTen Operator also provides support for upgrading replicated and non-replicated TimesTen Classic databases that are deployed in your Kubernetes namespace. For each replicated or non-replicated configuration, you have the option of choosing a manual or automated upgrade strategy. The processes and procedures differ depending on your configuration and upgrade strategy.

This chapter discusses and details the upgrade processes and procedures using YAML manifest files. If you are using Helm charts, see Use Helm in Your TimesTen Kubernetes Operator Environment.
