+## Commands and arguments
+
+Serverless Jobs allows you to customize the `command` and `args` instructions of your container image directly from the [Scaleway console](https://console.scaleway.com) and from the [Scaleway API](https://www.scaleway.com/en/developers/api/serverless-jobs/).
+
+- The `command` instruction defines the command, process, or script executed when your job starts.
+- The `args` instruction defines the arguments passed to the `command` instruction. Arguments can be passed as environment variables, as shown in the example below.
+
+**Example**
+
+```yaml
+env:
+- name: MESSAGE
+ value: "hello world"
+command: ["/bin/echo"]
+args: ["$(MESSAGE)"]
+```
+
+Refer to the [official Kubernetes documentation](https://kubernetes.io/docs/tasks/inject-data-application/define-command-argument-container/) for more information on commands and arguments behavior.

## Container Registry
Container Registry is the place where your images are stored before being deployed. We recommend using Scaleway Container Registry for optimal integration. See the [migration guide](/serverless-jobs/api-cli/migrate-external-image-to-scaleway-registry/) for full details.

+description: How to migrate from the legacy startup command system to the modern commands and arguments for Scaleway Serverless Jobs.

+
+The Serverless Jobs `v1alpha2` API introduces a new startup execution mechanism based on [commands and arguments](/serverless-containers/concepts/#commands-and-arguments), replacing the legacy startup command.
+
+The Scaleway console allows you to quickly and easily migrate your existing jobs to the new system.
+
+
+
+- A Scaleway account logged into the [console](https://console.scaleway.com)
+- [Owner](/iam/concepts/#owner) status or [IAM permissions](/iam/concepts/#permission) allowing you to perform actions in the intended Organization
+- An existing job that uses a startup command
+
+## How to migrate from startup command to commands and arguments
+
+1. Click **Jobs** in the **Serverless** section of the side menu. The jobs page displays.
+
+2. Click the name of the job you want to manage, then click the **Settings** tab.
+
+3. Scroll down to the **Configure advanced options**, then click the **Execution** tab.
+
+4. Click the **Upgrade** button. A pop-up displays.
+
+5. Split your existing startup command into a command (which corresponds to the `ENTRYPOINT` Docker instruction), and arguments (which correspond to the `CMD` Docker instruction).
+
+6. Click **Upgrade to the new format** to finish.
+
+Your Serverless Job now uses the command and arguments mechanism.
+
+## Migration examples
+
+### Simple command
+
+**Legacy startup command**
+
+```bash
+sleep 60s
+```
+
+**Corresponding command and arguments**
+
+```yaml
+command: [sleep]
+args: [60s]
+```
+
+### Complex command
+
+**Legacy startup command**
+
+```bash
+/app/migrate up --database "$DB_URL" --password "$DB_PASSWORD" --port 3002
+```
+
+**Corresponding command and arguments**
+
+```yaml
+ command: [/app/migrate]
+ args: [up, --database, "$(DB_URL)", --password, "$(DB_PASSWORD)", --port, 3002]
+```
+
+Refer to the [official Kubernetes documentation](https://kubernetes.io/docs/tasks/inject-data-application/define-command-argument-container/) for more information on command and arguments behavior and syntax.

### Job definition command
-In `v1alpha2`, the `command` field for Job definitions is **deprecated**.
+In `v1alpha2`, the `startup_command` field for Job definitions is **deprecated**.
It is replaced by two new fields, designed to give you more control and align with the [Serverless Containers](/serverless-containers/concepts/#serverless-containers) experience:
-* **`startup_command`**: A list of commands to start the application.
+* **`command`**: A list of commands to start the application.
* **`args`**: A list of arguments passed to the startup command.
This separation allows for a cleaner definition of entry points and arguments, mirroring standard container practices.
+Refer to the [dedicated documentation](/serverless-jobs/how-to/migrate-startup-command-to-command-args/) for more information on how to migrate from the legacy **startup command** to **command and arguments**.
+
### Job run troubleshooting
To assist with debugging, `v1alpha2` adds a **Job Run Reason** field.
