Details
This is how a placeholder blueprint becomes a real one. Devices reference a
blueprint by id, so correcting model or version in place keeps every
device attached; creating a second blueprint and re-pointing the devices
would not, because serial_number is unique per blueprint_id and the
move has to happen device by device.
