Request for Assistance: Backfilling Missing Event Property in Mixpanel
Hey dear team! We are missing a custom property on an event between 11/07/2025 to 11/12/2025 . And we are exploring ways to backfill the property to historical 94K events. What we tried:
export the event, backfill the property, and import to mixpanel with same $insertId, ends up with duplicate events
borrowed property: difficult on our data warehouse to combine the borrowed properties
Do we have a recommended way to backfill the missing property? Thanks!
