How to decommission a landing zone

To decommission your AWS Control Tower landing zone, follow the procedure given here.

  1. Navigate to the Landing Zone Settings page in the AWS Control Tower console.

  2. Choose Decommission your landing zone within the Decommission your landing zone section.

  3. A dialog appears, explaining the action you are about to perform, with a required confirmation process. To confirm your intent to decommission, you must select every box and type the confirmation as requested.

    Important

    The decommissioning process cannot be undone.

  4. If you confirm your intent to decommission your landing zone, you are redirected to the AWS Control Tower home page while decommissioning is in progress. The process may require up to two hours.

  5. When decommissioning has succeeded, you must delete remaining resources manually before setting up a new landing zone from the AWS Control Tower console. These remaining resources include some specific S3 buckets, organizations, and CloudWatch Logs log groups.

    Note

    These actions may have significant consequences for your billing and compliance activities. For example, failure to delete these resources can result in unexpected charges.
