Is it possible to update resources via cloudformation template?

Is it feasible to modify resources like redshift cluster via AWS cloudformation template if the resources were created manually and not by AWS cloudformation templates? I want change node type of cluster and modify maintenance window.

Solution

  • you would need to import cloudFormation resources using resource import https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/resource-import.html

    you still need a valid CloudFormation template
