NOTE: Some Milestone next steps may be marked as "N/A" for "Not Applicable" with an explanation after a trailing "-".  For example, "N/A - Grandfathered" means that the step was skipped due to the fact that the process changed after the step would have been completed and it has been "Grandfathered" in (meaning accepted as N/A) as acceptable.
