CFnでリソースを削除してから作成するように設定を変更できるが、これを実行した場合には、ロールバックできなくなるのではないか?
replacementStrategy
The order of replacement when a resource update necessitates replacing the existing resource with a new resource. For example, updating a resource property that is listed in createonlyProperties results in a new resource being created to replace the existing resource.
By default, when updating a resource that requires replacement, AWS CloudFormation first creates the new resource, and then delete the old resource. However, some resources can only exist one at a time in a given account/region. For these resources, this attribute can be used to instruct AWS CloudFormation to delete the existing resource before creating its replacement.
For more information on how resources are updated, see Update behaviors of stack resources in the AWS CloudFormation User Guide.
