We want to take this historical enrollment record from Amplitude/Metabase and backfill our newly created local EnrollmentEvent table in the app.

The backfill should be for any enrollment that occurred prior to when the EnrollmentEvent table went into prod: 09/18/2024, version 2024.09.2

The general approach could be something like:

1. Download all enrollment events from Metabase as JSON
2. Transform into a Django fixture JSON structure
3. Download the production database locally
4. Use manage.py loaddata <fixtures> to load the fixtures in
5. Re-upload and overwrite the production database

Acceptance criteria

• All historical enrollments (~153 as of 09/22/2024) are represented accurately within the prod Admin interface EnrollmentEvents table.
• The Amplitude/Metabase property event_time is used for the EnrollmentEvent.enrollment_datetime value
• EnrollmentEvent.enrollment_method is DIGITAL for all backfilled events

Historical enrollment events have been back-filled into benefits.calitp.org, which is now showing a total of 193 enrollments going back to December 2021:

Note that Metabase, as of 11/15/2024 at 13:00 Pacific, is showing a total of 192 enrollments. There was an enrollment this morning that has not yet made it from Amplitude --> Metabase 😉
