 Kubernetes recommends using server-side apply for more control over the field manager. After adopting the chart resources, you can run the following command to apply the chart:
+
 ```
 helm template aws-vpc-cni --include-crds --namespace kube-system eks/aws-vpc-cni --set originalMatchLabels=true | kubectl apply --server-side --force-conflicts --field-manager Helm -f -
 ```
 
 ## Migrate from Helm v2 to Helm v3
+
 You can use the [Helm 2to3 plugin](https://github.com/helm/helm-2to3) to migrate releases from Helm v2 to Helm v3. For a more detailed explanation with some examples about this migration plugin, refer to Helm blog post: [How to migrate from Helm v2 to Helm v3](https://helm.sh/blog/migrate-from-helm-v2-to-helm-v3/).
