# Transition a Standby Server to Active Mode

If the server is active, when you connect to it, Cortex XSOAR appears as normal. After logging in, if the server is in standby mode, you will reach the **This is currently the Backup Server** page.

1. On the standby server being transitioned to active mode, from the **This is currently the Backup Server** page, click **Make this the production server**.
2. In the Switch Hosts dialog box, in the text box, type **`Switch Hosts`**.

   Cortex XSOAR appears and the host is now active.

   <div data-gb-custom-block data-tag="hint" data-style="info" class="hint hint-info"><h3>Note</h3><p>If accounts are showing as offline, follow these steps:</p><ol><li>Log in to each host server that has been switched to Primary.</li><li>Go to <strong>Settings</strong> → <strong>About</strong>+Troubleshooting → <strong>Server Configuration</strong>.</li><li>Edit the <strong>Main account</strong> server setting to point to the hostname of the now active Cortex XSOAR main host.</li></ol><p>After these steps, the hosts should display as active on the Account Management page, and connect correctly to the main host.</p></div>
3. In the backup server environment, go to Settings → About → **Troubleshooting**.
4. For the External Host Name key, update the value to the host name of the backup server (the new production server).

   The backup server is unaware of its external host name.

   After a successful switch, the backup server is now live.

## 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/xsoar-6-administrator-guide/6.12/onboard-cortex-xsoar/onboarding-in-cortex-xsoar/disaster-recovery-and-live-backup/transition-a-standby-server-to-active-mode.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.
