# Upgrade XDR Collectors

{% hint style="info" %}

### Notice

Ingestion of logs and data requires a Cortex XDR Pro per GB license.
{% endhint %}

After you install the Cortex XDR Collector and the XDR Collector registers with Cortex XDR, you can upgrade the XDR Collector software for on-premise Windows or Linux collector machine. You need to create a new installation packages and push the XDR Collector package to up to 500 collector machines from Cortex XDR.

1. Create an XDR Collector Installation Package for each operating system version where you want to upgrade the XDR Collector.

   Note the installation package names.
2. Select **Settings** → **XDR Collectors** → **Administration**.

   If needed, filter the list of on-premise collector machines. To reduce the number of results, use the collector machine name search and filters at the top of the page.
3. Select the collector machines you want to upgrade.

   You can also select collector machines running different operating systems to upgrade the XDR Collectors at the same time.
4. Right-click your selection and select **Upgrade Collector version**.

   For each platform, select the name of the installation package you want to push to the selected on-premise collector machines.

   <div data-gb-custom-block data-tag="hint" data-style="info" class="hint hint-info"><h3>Note</h3><p>The XDR Collector keeps the name of the original installation package after every upgrade.</p></div>
5. **Upgrade**.

   XDR distributes the installation package to the selected collector machine at the next heartbeat communication with the XDR Collector. To monitor the status of the upgrades, go to **Response** → **Action Center**. From the **Action Center** you can also view additional information about the upgrade (right-click the action and select **Additional data**) or cancel the upgrade (right-click the action and select **Cancel Collector Upgrade**).

## 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://cortex-docs.paloaltonetworks.com/cortex-xdr-3.x/cortex-xdr-3.x-documentation/data-management/xdr-collectors/manage-xdr-collectors/upgrade-xdr-collectors.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.
