Change sets before update
This revision card explains Change sets before update. It starts from the need that blind stack update can replace a database or break a critical resource. A change set shows adds/modifies/removes before you execute; review replacements carefully. The how-to section covers how to create change set , then inspect , then execute only when replacements are expected. An example on the card is renaming a logical ID shows Delete+Add — stop and use retain/rename strategy.
