+## Upgrade
+
+Metacontroller is pulled from [Kubeflow Pipelines third-party folder](https://github.com/kubeflow/pipelines/tree/master/manifests/kustomize/third-party/metacontroller). To update this component specify the desired KFP version and run the following command in console from the root directory **/**:
+
+```bash
+export KFP_VERSION=2.0.0-alpha.3   # specify KFP version
+kpt pkg update ./contrib/metacontroller@${KFP_VERSION}
+```
+
+Alternatively, you can copy the content from [Kubeflow Pipelines third-party folder](https://github.com/kubeflow/pipelines/tree/master/manifests/kustomize/third-party/metacontroller) by choosing the appropriate `TAG` in that repository.
