1. Archived the predecessors (112 series) by renaming with an "_19" specifier, marking metadata as "discontinued", and segregating in the catalog.
2. Created one-for-one replacements. 
3. Added newly-reported series (113).
4. Transplanted global concept aliases to active series. 
5. Synchronized seasonally adjusted supplements.

Notable properties (for full list, see background):

• Measurements: No change
