Reattaching a retained cloudformation resources, back to a cloudformation stack

Question

We are retaining some of the cloudformation resources for safety reasons.

This is achieved using DeletionPolicy: Retain

Is there any way to reattach those retained resources to a new/existing stack?

Answer 1

Yes, you can create a new cloudformation stack or update an existing stack with resources that are not managed by Cloudformation. This is done using Resource Import.

Here is the list of such resources that can be imported: Resources that support Import operation.
