Case Snapshot
Executive Summary
A top 50 global airport accelerated its massive SAP transformation from ECC to S/4HANA by utilizing SLaiCE for targeted enterprise data carve-outs. SLaiCE enabled the airport to isolate current financial year data for a lean production system and carve out specific historical data for legal retention, directly resulting in a 40-50% reduction in total migration cost and time.
The Challenge: Decades of data complicating SAP S/4HANA migration
The top 50 global airport relied on an SAP ECC system installed 20 years prior, accumulating massive historical datasets spanning from 2005 to 2026. To migrate successfully to SAP S/4HANA, the airport needed to separate active operational data from historical records without exposing the organization to compliance risks or extended system downtime. The specific migration complexities included:
- Mixed data volumes: Historical enterprise data from FI, Logistics, Projects, custom tables, and add-ons were heavily intertwined within the 20-year-old system.
- Strict audit requirements: All data carve-outs required rigorous review and explicit approval by both internal and external auditors before execution.
- Security mandates: Enterprise data needed to remain strictly within the highly secure SAP landscape throughout the entire migration process.
“Our airport selected SLaiCE solution for our migration from SAP ECC to SAP S/4HANA. Two factors were decisive: the data stays within the SAP landscape throughout the migration, and the approach supports completion within seven to eight months.”— Customer Feedback
