We recently changed some of our event property names and now have data in duplicate properties. I don’t want to lose the old data under the old property and would like to merge it with the new property.
For example, we have “Product ID” stored in the old property (called “Product ID”) as well as in the new property (called “Products.product_id”). What is the best way to collapse these two properties into one so that I can keep all the historical data from the old property value?
