# Update an existing stack in Infrastructure Composer in CloudFormation console mode
<a name="composer-cfn-mode-update"></a>

Follow the instructions in this topic to update an existing CloudFormation stack.
**Note**  
If your file is saved locally, we recommend using [AWS Toolkit for Visual Studio Code](using-composer-ide.md).

1. Go to the [CloudFormation console](https://console.aws.amazon.com/cloudformation) and log in.

1. Select the stack you want to edit.

1. Select the **Update** button. Doing this will take you to the update stack wizard.

1. On the right, select **Edit in Infrastructure Composer**.

1. Select the button below that's labeled **Edit in Infrastructure Composer**. This will take you to Infrastructure Composer in CloudFormation console mode.

1. Here, you can drag, drop, configure, and connect resources ([cards](using-composer-cards-intro.md)) from the **Resources** pallete.
**Note**  
See [How to compose](using-composer-basics.md) for details on using Infrastructure Composer, and note that Lambda-related cards (**Lambda Function** and **Lambda Layer**) require code builds and packaging solutions that are not available in Infrastructure Composer in CloudFormation console mode. These cards can be used in the [Infrastructure Composer console](https://aws.amazon.com/application-composer/) or the AWS Toolkit for Visual Studio Code. For information on using these tools, refer to [Where you can use Infrastructure Composer](using-composer.md).

1. When you are ready to export changes to CloudFormation, select **Update template**.

1. Select **Confirm and continue to CloudFormation**. This will take you back to the **Update stack** workflow with a message confirming your template was successfully imported.
**Note**  
Only templates with resources in them can be exported.

1. In the **Update stack** workflow, select **Next**.

1. Review any listed parameters and select **Next**.

1. Select **Next** after providing the following information:
   + Tags associated with the stack
   + Stack permissions
   + The stack's failure options
**Note**  
For guidance on managing stacks, see [CloudFormation best practices](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/best-practices.html) in the *CloudFormation User Guide*.

1. Confirm your stack details are correct, check acknowledgements at the bottom of the page, and select the **Submit** button.

CloudFormation will begin updating the stack based on the updates you made in your template.
