Merge !60 (merged) first.
This migration adds transforms the existing data from points to match record. It runs this in a Django migration, meaning the data migration will automatically run as part of the CI/CD process. It also includes a way to rollback this migration if we ever need to. I tested both by running it on my local copy of the database.
I copied some of the code rather than import it because I don't want the result of this migration to change in the future if someone changes the estimation function.
