The system is up and running with existing datasource, traits, segments, destination and profile merge rules. But, there is no proper naming convention followed so, I want to update the name of all building blocks. I've few doubts -
Changing the name should have no impact on the way that they are linked. Everything is done via IDs, and the naming is just for reference in the UI. As for recommended guidelines, we leave that up to the customer's discretion. Every customer may utilize the system differently, and they can thus organize their traits and segments how they choose.
