Upgrade the TimesTen CRDs

To upgrade the TimesTen CRDs in your cluster, use the ttcrd chart from the new release.

Note the following:

You cannot downgrade TimesTen CRDs.
Since CRDs are cluster-scoped, if you delete TimesTen CRDs from your Kubernetes cluster, all TimesTenClassic objects that are deployed in this cluster are also deleted.

Confirm the current ttcrd release.

helm list

The output is similar to the following:

NAME    NAMESPACE       REVISION        UPDATED                                 STATUS   CHART                   APP VERSION

The ttcrd chart version is 2211340.1.0 and appversion is 22.1.1.34.0 corresponding to TimesTen release 22.1.1.34.0.

On your development host, change to the new_kube_files/helm directory.
```
cd new_kube_files/helm
```
