C3D-HCWA-TEXT · HCWA migration 5/5: single-line text done

Convert MText to single-line DBText (HCWA: all required text must be single line text); road names to ROAD_TEXT

Result

  MText -> DBText 'SPRINGDALE RD (80' R/W)' on ROAD_TEXT
TEXT migration: 1 MText converted to 1 single-line DBText entities.
