- Verified that the theory was correct by uploading two copies of a file and migrating the first one, before applying the patch. The second one's data was nuked and it couldn't be migrated.
- Applied patch.
- Uploaded two copies of a new file, migrated the first one (no data deletion), migrated the second one (data correctly deleted).
- Uploaded two copies of another new file, `bin/remove destory'd` the first one (no data deletion), then did it to the second one (data correctly deleted).
