# Patch Management

### Creating an Application Patch

```bash
$ cloudio create-patch -a my-app
```

Running the above command generates an application patch as a zip file. The zip contains all the metadata in various .json & .js files. You can extract and check into your source control system e.g. GitHub.

### Verifying an Application Patch

Once a patch is generated from a source instance, you can verify it against a target instance to review the changes to be applied to the target instance.

```bash
$ cloudio verify-patch -a my-app
```

### Applying an Application Patch

Once reviewed and approved, you can apply the patch using the following command

```bash
$ cloudio patch -a my-app
```
