usePreviousTemplate

Reuse the existing template that is associated with the stack that you are updating.

When using templates with the AWS::LanguageExtensions transform, provide the template instead of using UsePreviousTemplate to ensure new parameter values and Systems Manager parameter updates are applied correctly. For more information, see AWS::LanguageExtensions transform.

Conditional: You must specify only one of the following parameters: TemplateBody, TemplateURL, or set the UsePreviousTemplate to true.
