# Upgrade your tenant

When you purchase new entitlements, Cortex XSIAM automatically applies them to your tenant through a seamless upgrade process. If any downtime is required, you’ll receive advance notice and can choose a convenient time to proceed with the upgrade.

A banner notifies you that an upgrade is scheduled. To see details of the upgrade schedule, click **view upgrade details**. You can continue with the update schedule, or take one of the following actions:

* To upgrade immediately, click **Upgrade now**.
* To schedule an upgrade, select a start date and time from the calendar.

Keep in mind the following during the upgrade process:

* The gateway may experience up to two hours of downtime during the installation.
* The upgrade will occur automatically on the scheduled time and date unless you change it. The product will also display a banner 24-hours before the upgrade occurs.
* The development tenant associated with the upgraded production tenant will also be upgraded.
* Pairing Prisma Cloud Compute with Cortex XSIAM is not supported in XSIAM 3.X versions.

## 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-xsiam/learn-about-cortex-xsiam/cortex-xsiam-product-licenses/upgrade-your-tenant.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.
