Accelerating HR Analytics with Informatica to Databricks Modernization : 510.818.9480 : info@kpipartners.com : www.kpipartners.com — Director, HR Analytics KPI Partners helped us modernize our HR analytics platform while ensuring continuity during our ERP transition. Their structured approach to migrating our Informatica workloads to Databricks enabled us to move away from legacy ETL and establish a more scalable data foundation. CLIENT A global biopharmaceutical organization delivering clinical development and commercialization services. OVERVIEW During a PeopleSoft to Workday ERP transition, the organization modernized its HR analytics platform by migrating 658 Informatica PowerCenter mappings to Azure Databricks using KPI’s Informatica to Databricks Migration Accelerator. In addition to migrating legacy ETL pipelines, the program required redesigning parts of the data model and transformation logic to align with Workday’s data structures. KPI systematically assessed, converted, and validated all mappings over approximately six months, replacing tightly coupled Informatica workflows with a Lakehouse architecture built on PySpark and Delta Lake. The new platform enabled decommissioning of the legacy ETL environment, improved scalability through auto scaling Databricks clusters, and ensured uninterrupted workforce reporting through parallel validation and reconciliation. : 510.818.9480 : info@kpipartners.com : www.kpipartners.com CHALLENGES SOLUTION OVERVIEW Workday data model changes required downstream pipeline re-engineering 658 complex Informatica PowerCenter mappings tightly coupled with PeopleSoft Zero tolerance for HR reporting disruption during ERP transition High ETL licensing, infrastructure, and maintenance overhead Long batch windows and limited scalability during peak cycles Limited documentation increased migration complexity Si gnificant data model misalignment between PeopleSoft and Workday Sensitive HR data required strict governance and access controls KPI Partners led the migration of 658 Informatica PowerCenter mappings to Azure Databricks through its Informatica to Databricks Migration Accelerator. The team converted legacy ETL workflows into PySpark and SQL using standardized conversion patterns and implemented parallel validation and reconciliation to ensure zero reporting disruption during the ERP transition. KPI built a Lakehouse architecture with bronze, silver, and gold layers, redesigned Workday data ingestion, and aligned HR data models to the new ERP structures.
