The Challenge
The airport was moving from SAP ECC, installed 20 years earlier, to SAP S/4HANA as part of a large SAP transformation.
Its SAP ECC system held business data from 2005 to 2026. The new landscape needed only the right slices of that history, and every step had to stand up to audit.
What SLaiCE Did
SLaiCE carried out two carve-outs from the SAP ECC system:
- Current financial year. Moved only the 2026 data out of the 2005–2026 dataset, across FI, logistics, projects, custom tables and add-ons, to build a lean production system.
- Nine years of history, plus an archive. Moved complete business data for 2017–2025 from more than 700 tables across FI, logistics and projects, and created a read-only archive system for 2005–2016 to meet legal retention.
Every carve-out was audited by internal and external auditors.
Customer Feedback
“Our airport selected SLaiCE 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. SLaiCE also enabled us to carve the historical data to a defined scope aligned with our retention requirements, which was reviewed and approved internally before execution. The outcome has been well received by our finance leadership.”
