# astro deployment runtime migrate

<Info>This command is available only if you're authenticated to an Astro Private Cloud installation.</Info>

Initializes the Runtime migration upgrade process on any Deployment on Astro Private Cloud.

## Usage

Run `astro deployment runtime migrate --deployment-id=<deployment-id>` to initialize the Runtime upgrade process. To finalize the Runtime upgrade process, complete all of the steps in [Migrate to Astro Runtime](https://www.astronomer.io/astro-private-cloud/v-0-37/migrate-to-runtime).

The Astro CLI lists only the available Runtime versions that are later than the version currently specified in your `Dockerfile`.
