title: How to remove a resource without deleting it during a cloudformation stack update
body: <p>I have a cloudformation template that creates an S3 bucket as part of a cloudformation stack. On the new version of my template, I 'm planning to migrate my application from S3 to EFS. </p>
  
  <p>Is there a way to remove the S3 bucket resource from the template, without having it deleted? Ideally, I would like my older users to have the s3 bucket available after they upgrade, but for the new users to not have it at all. It looks like DeletionPolicies could help here, but the documentation on it says that it only applies to stack deletion, but not upgrades.</p>
