## Upgrade Prerequisites

Before you perform the upgrade, you must create a backup of your files, data, and configurations in
case you need to restore to them.

## Upgrade Steps

Follow these steps to perform the upgrade:

1.  In Anypoint Studio, create a Mule project.

2.  In the **Mule Palette** view, click **Search in Exchange**.

3.  In **Add Dependencies to Project**, enter `twilio` in the search field.

4.  In **Available modules**, select **Twilio Connector** and click **Add**.

5.  Click **Finish**.

6.  Verify that the Twilio Connector dependency version is 4.0.0 in the `pom.xml` file in the Mule
    project.

Studio upgrades the connector automatically.

## Verify the Upgrade

After you install the latest version of the connector, follow these steps to verify the upgrade:

1.  In Studio, verify that there are no errors in the **Problems or \*Console** views.

2.  Verify that there are no problems in the project `pom.xml` file.

3.  Test the connection to verify that the operations work.

## Revert the Upgrade

If it is necessary to revert to the previous version of Twilio Connector, change the `4.0.0`
dependency version in the project’s `pom.xml` file to the previous version.

You must update the project’s `pom.xml` file in Anypoint Studio.
