One of the documents in your collection has an _id based upon an older database design and you want to change it. You write an update command to find the document and replace the _id but the _id isn’t changed. How should you fix the issue?

  •  Set the replace option to true.
  •  Use the replaceOne() command instead.
  •  You can’t. Once set, the _id field cannot be changed.
  •  Use the updateOne() command instead.
