#### Other migrations

If you see errors like `rendered manifests contain a resource that already exists` during installation, you may need to forcibly take ownership.

The script below can handle this for you. Replace `RELEASE` and `NAMESPACE` with the name and namespace of the release:

```

Use `istioctl` to generate the manifests for the new configuration profile:

```bash
istioctl manifest generate -f manifests/profiles/minimal.yaml
```

After running the command, the Helm charts are rendered using `manifests/profiles/minimal.yaml`.

##### --set syntax

The CLI `--set` option can be used to override settings within the profile.
