Migrating a legacy data estate to Google Cloud

Business-critical data pipelines, a hard shutdown date, and a system that never stops. Moving an on-premises Hadoop estate without pausing the business or hand-migrating the pipelines.

Data Transformation

OUTCOME

6,500

Data processing jobs migrated to cloud

50%

Faster migration

33%

Ahead of the delivery deadline

CONTEXT

An on-premises Hadoop estate was being shut down, with thousands of processing jobs needing to move to Google Cloud before the date. Migrating pipelines by hand is slow and error-prone at that scale, and the existing architecture was fragmented across siloed on-premises systems with limited cloud-native skills in-house. The data foundation had to modernize without slowing the business or introducing risk into a live payments environment.

SOLUTION

Synapt Data Transformation, deployed as a GenAI migration accelerator that turned a fixed deadline into a controlled, repeatable process.

  • Legacy code translated into Google Cloud-native form automatically, with minimal manual rework

  • Accuracy checks running as part of the pipeline, not as a separate review step

  • Monitored cutover with a hyper-care period to surface issues early

  • Engineers migrating faster with less dependence on scarce SMEs
