What to change
An event name is a dependency shared by configuration, reports and any downstream exports. Before combining old and new observations, ask whether the underlying definition also changed. If the meaning is equivalent, document the mapping and transition. If it is different, retain separate measures and explain the break. Validate a current fictional event against the dashboard's actual selection rule, not merely against a debugger that displays all incoming names.
A worked example
Illustrative example
Illustrative test: A test event appears in the intended current measure with the documented meaning.
How to check the result
The report explains the transition without disguising a definition change as business performance.
A mistake to avoid
Combining similarly named events can join fundamentally different actions.
Your action checklist
Use these checks to prepare a discussion with your team or supplier. Tick a check when you have recorded the decision or evidence, rather than when a feature has simply been promised.
