Persistable error when trying to publish

But how do you migrate in this situation?

Is it going to have to be:

  • Publish a new version that migrates from the old data to new data (v1)
  • Publish a new version that eliminates the old data (v2)
  • Publish a new version that adjusts the enum?

Or does that map have to be there in the save data forever? In which case, I can never adjust the enum?
