I have created an event with an event property called “Project UUID”. I now want to make this property more generic. What happens if I change this property in my code by replacing it with “Entity UUID”. From what I understand, old events will style have the “Project UUID” property and the “Entity UUID” property will apply only to new events. What is the consequence when I want to query the event in a dashboard ? Can I merge the old version of the property with the new one ?
