Upgrade the TimesTen CRD

You can upgrade the TimesTen CRD that is installed in your Kubernetes cluster. In TimesTen releases 22.1.1.27.0 and greater, the TimesTenClassic CRD contains different schema versions. The v5 schema version is the most current. The v4 and v3 schema versions are available to facilitate compatibility with previous releases of the TimesTen Operator. The v3 schema version is deprecated and will be removed in a future release. For more information, see About Upgrading from Previous Releases.

Note the following:

• You cannot downgrade a TimesTen CRD.

• Since CRDs are cluster-scoped, if you delete a TimesTen CRD from your Kubernetes cluster, all TimesTenClassic objects that are deployed in this cluster are also deleted.

This example uses YAML manifest files for the upgrade. To use Helm charts, see Use Helm in Your TimesTen Kubernetes Operator Environment.

1. On your development host, change to the directory that contains the YAML manifest files for the upgrade. In this example, change to the new_kube_files/deploy directory.

   cd new_kube_files/deploy

2. Replace the TimesTen CRD that is installed in your Kubernetes cluster.

   kubectl replace -f crd.yaml

   The output is the following:

   customresourcedefinition.apiextensions.k8s.io/timestenclassics.timesten.oracle.com replaced

Congratulations! You successfully upgraded the TimesTen CRD.
