You can now specify how AWS CloudFormation manages your resources when they need to be replaced during an update operation. Using the UpdateReplacePolicy attribute, you can specify if CloudFormation should delete, retain, or create a snapshot of old resources once the new ones have been created. The behavior defaults to delete when UpdateReplacePolicy is not specified.
For more information, visit the UpdateReplacePolicy Attribute documentation page.
