# Downgrade to a previous version
<a name="rstudio-version-downgrade"></a>

You can manually downgrade the version of your existing RStudio application to the `2024.04.2+764.pro1` version. 

**To downgrade to a previous version**

1. Delete the `RStudioServerPro` application that's associated with your existing domain. For information about how to find your domain ID, see [View domains](domain-view.md).

   ```
   aws sagemaker delete-app \
       --domain-id domainId \
       --user-profile-name domain-shared \
       --app-type RStudioServerPro \
       --app-name default
   ```

1. Pass the corresponding `2024.04.2+764.pro1` ARN for your Region as part of the `update-domain` command. For a list of all available ARNs, see [Versioning](rstudio-version.md#rstudio-version-new). You must also pass an execution role ARN for the domain that provides permissions to update the domain. 

   ```
   aws sagemaker update-domain \
       --region region \
       --domain-id domainId \
       --domain-settings-for-update "{\"RStudioServerProDomainSettingsForUpdate\":{\"DefaultResourceSpec\": {\"SageMakerImageArn\": \"arn-for-2024.04.2+764.pro1-version\", \"InstanceType\": \"system\"}, \"DomainExecutionRoleArn\": \"execution-role-arn\"}}"
   ```

1. Create a new `RStudioServerPro` application in the existing domain. The RStudio version defaults to `2024.04.2+764.pro1`.

   ```
   aws sagemaker create-app \
       --domain-id domainId \
       --user-profile-name domain-shared \
       --app-type RStudioServerPro \
       --app-name default
   ```

Your `RStudioServerPro` application is now downgraded to version `2024.04.2+764.pro1`.
