USE CASE: DATA MODERNIZATION

Legacy ETL to cloud-native pipelines

Sanciti AI migrates legacy ETL workflows to cloud-native data pipelines, preserving every transformation rule and proving the outputs match. A financial services company completed its ETL migration with zero data loss at 50% lower cost than the manual rewrite estimate.

Why legacy ETL is hard to leave

Proprietary ETL platforms get more expensive each year, and the transformation logic inside them cannot be moved easily. Years of business rules live in jobs that nobody has documented in their current state.

Testing is the other gap. Many teams still check transformations manually on a sample of records, so most data paths are never tested. In regulated industries, one missed transformation error can end up in a regulatory report.

How Sanciti AI migrates legacy ETL

LEGMOD ran the migration with one rule above the rest: data lineage had to be preserved at every step.
1

RGEN

Parsed the ETL workflows and extracted transformation logic, data lineage and metadata into structured documentation.
2

CodeGen

Generated cloud-native pipeline code built for distributed processing and larger data volumes.
3

TestAI

New architecture-aligned code, modern stacks, secure by default
4

LEGMOD

Validates the modernized application end to end with autonomous tests

FAQS

Yes. RGEN extracts the transformation logic and lineage from legacy ETL workflows, and CodeGen rebuilds them as cloud-native pipelines.

TestAI compares legacy and new pipeline outputs across every transformation path. The financial services migration reached 90%+ automated parity coverage with zero data loss.

In the financial services project, the legacy license costs and vendor dependency were removed after the move to open, cloud-native processing.

Yes. Every transformation migrated is recorded, which supports reporting and regulatory reviews.
