version 4.x.

## Supported Upgrade Paths

<table><colgroup><col> <col></colgroup><thead><tr><th>From Version</th><th>To Version</th></tr></thead><tbody><tr><td><div><div><p>3.x</p></div></div></td><td><div><div><p>4.x</p></div></div></td></tr></tbody></table>

## Changes in This Release

- The connector now supports multiple child organizations by specifying the **Account Id** field.

- The `SFDC-MARKETING-CLOUD:THROTTLED` error is removed.

## Upgrade Prerequisites

Before you perform the upgrade, you must:

1.  Create a backup of your files, data, and configuration in case you must restore to the previous
    version.

2.  Install Salesforce Marketing Cloud Connector 4.x.x.

## Upgrade Steps

Follow these steps to perform the upgrade from Salesforce Marketing Cloud Connector 3.x.x to
Salesforce Marketing Cloud Connector 4.x.x:

1.  In Anypoint Studio, create a Mule project.

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

3.  In the **Add Dependencies to Project** window, enter `Salesforce Marketing Cloud` in the search
    field.

4.  In the **Available modules** section, select **Salesforce Marketing Cloud Connector** and click
    **Add**.

5.  Click **Finish**.

6.  Verify that the `mule-sfdc-marketing-cloud-connector` dependency version is `4.x.x` in the
    `pom.xml` file, in which the first `x` is the minor release number and the second `x` is the
    patch release number.

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.  Check the project `pom.xml` file and verify that there are no problems.

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

## Troubleshooting

If there are problems with caching the parameters or caching the metadata, try restarting Studio.

## Revert the Upgrade

If it is necessary to revert to the previous version of Salesforce Marketing Cloud Connector, change
the `mule-sfdc-marketing-cloud-connector` dependency version `4.x.x` in the project’s `pom.xml` file
to the previous version.
