{% endcontent-ref %}

{% stepper %}
{% step %}

### Access your Node

{% endstep %}

{% step %}

### Begin the Upgrade Process

```bash
sudo nodectl upgrade_nodectl
```

{% endstep %}

{% step %}

### Choose the Correct Upgrade Path

You will be prompted to select between two available versions:

* The **latest version**
* The **last known upgrade path version**

{% hint style="warning" %}
⚠️ **Important:** Select the version that follows the recommended upgrade path. Skipping versions may result in misconfiguration or compatibility issues.
{% endhint %}

* Press the corresponding number key (no need to press Enter).
* Press `y` to confirm your selection.
  {% endstep %}

{% step %}

### Verify the Upgrade Signature

After download, ensure the following message appears:

```
SUCCESS - AUTHENTIC NODECTL
```

🚫 If you see:

```
INVALID SIGNATURE - WARNING
```

<mark style="color:red;">**Stop immediately**</mark>.\
Do **not** run additional commands.\
Report the issue via the **Constellation Network Official Discord** to verify the integrity of your upgrade and prevent potential malicious activity.
{% endstep %}

{% step %}

### Tessellation Upgrade (If Prompted)

You may now be asked whether to upgrade Tessellation as part of the upgrade flow.

* 🛑 **If not required:** Skip to next step
* ✅ **If required:** Press `y` and follow the prompts

You may optionally refer to the full [Tessellation upgrade guide](/run-a-node/validator-node-guides/operational-guides/upgrade-tessellation-guide.md) for details before continuing
{% endstep %}

{% step %}

### Restart Auto Restart Feature (Optional)

If you’re using the `auto_restart` feature, it’s recommended to manually restart it to ensure any upgrade-related updates are applied:

```bash
sudo nodectl auto_restart restart
```

{% endstep %}
{% endstepper %}

## 🎉 Congratulations!

Your node is now running the **latest version of nodectl**, fully updated and ready for continued participation in the Constellation Network.

***

You can confirm your version using:

```bash
nodectl version
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.constellationnetwork.io/run-a-node/validator-node-guides/operational-guides/upgrade-nodectl-version.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
