Updating configuration of .yaml deployment Files

You may want to update the configuration of your cluster. For example, you could change log levels or replicas. To change the configuration or your cluster, take these steps.

When a new version of a chart is released, or when you want to change the configuration of your release, you can use the `helm upgrade` command. An upgrade takes an existing release and upgrades it according to the information you provide. Because Kubernetes charts can be large and complex, Helm tries to perform the least invasive upgrade. It will only update things that have changed since the last release. For more information, see ['helm upgrade' and 'helm rollback': Upgrading a Release, and Recovering on Failure](https://helm.sh/docs/intro/using_helm/#helm-upgrade-and-helm-rollback-upgrading-a-release-and-recovering-on-failure) on the Helm Docs site.

**Procedure**

Navigate to the directory where the Helm chart is located (./production/helm-deployment).
To upgrade the Z APM Connect DG or modify your configuration, run the `helm upgrade` command, including the release name and chart path as arguments.

```
helm upgrade --namespace <desired project> -f <config yaml> <name> <chart location>
```

For example,

```
helm upgrade --namespace ibm-zapm -f values.yaml zapm ./zapm-dg-25.2.0.tgz
