# Instance Upgrade

Upgrade the instance type of a ProSBC deployment in AWS. With TBOS10 the license stays valid; on earlier versions, contact TelcoBridges support for a replacement.

This page guides people to upgrade the ProSBC instance in AWS. Before starting this procedure you must have access to the AWS console.

{% hint style="info" %}
**Licensing.** With **TBOS10**, changing the instance type keeps the license valid — no new license is required. On earlier versions the instance change invalidates the license; contact the TelcoBridges support team to get a new one before you proceed.
{% endhint %}

Before starting the upgrade, confirm that the target instance type is on the supported list. See [Supported instance types](/initial-installation/1.-instructions-by-platform/cloud-installation/cloud-aws.md#instantiate-a-prosbc) on the Cloud - AWS page.

All supported instance types (m5, m6i, m7i, m8i) have enhanced networking enabled by default, so no SR-IOV preparation is needed.

1\. Login to your AWS account.

2\. Go to EC2 and select the instance that you want to upgrade. Stop the instance.

3\. Click on Action and go to Instance Settings -> Change instance type

4\. Select the new instance type. It must be one of the supported families (m5, m6i, m7i, m8i) in a size from `.large` to `.12xlarge`. Upgrading across families — for example m5.xlarge to m7i.xlarge — is supported.

## 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://prosbcdocs.telcobridges.com/initial-installation/1.-instructions-by-platform/cloud-installation/cloud-aws/instance-upgrade.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.
