A particular obstacle on this journey was a reporting data mart which relied on copious amounts of legacy SAS code that applied sophisticated business logic transformations for membership, claims, premiums and reserves. This core data mart was driving many of our critical reports and analytics. In this session we will share the unique and somewhat unexpected challenges and complexities we encountered in migrating this legacy SAS code. How our partner (T1A) leveraged automation technology (Alchemist) and some unique approaches to reverse engineer (analyze), instrument, translate, migrate, validate and reconcile these jobs; and what lessons we learned and carried from this migration effort. |
