# Manage an existing landing zone using CloudFormation
<a name="lz-apis-cfn-launch-existing"></a>

You can use CloudFormation to manage a landing zone that you have already launched by importing the landing zone in a new or existing CloudFormation stack. Review [ Bringing existing resources into CloudFormation management](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/resource-import.html) for details and instructions. 

To [detect and resolve drift within a landing zone](https://docs.aws.amazon.com/controltower/latest/userguide/drift.html), you can use the AWS Control Tower console, the AWS CLI, or the [`ResetLandingZone` API](lz-api-reset.md).
