- Make a PR to remove all uses of the column in the codebase in a separate PR. This mostly helps with code cleanliness. This should be merged ahead of the migration prs, but we don't need to worry about whether it is deployed first.
- First, if the column is either not nullable, or doesn't have a `db_default` set, then make a PR to make it nullable via `null=True`.
