If a doc is changed drastically, it can move around on disk and then be returned by a cursor a second time.

You can either write an idempotent migration or open your own cursor and use snapshotting: https://docs.mongodb.org/manual/core/read-isolation-consistency-recency/ (pay heed to the warnings listed)
