Re-Platforming for Cost Reduction: A European Financial Services Transformation

In today’s financial services landscape, institutions are under immense pressure to modernize their data infrastructure. Rising operational costs, outdated platforms, and the need for next-generation digital use cases are pushing enterprises to rethink their strategies. For one of northern Europe’s leading financial services groups, the challenge was clear: how to replace its legacy data systems with a scalable, cost-efficient platform without disrupting critical business operations.

This case study uncovers how the organization successfully navigated this transition with Snowflake and LTIMindtree.

The Challenges

Escalating Costs and Limited Scalability

The legacy on-premises platform was nearing its end of life, burdening the enterprise with high storage and management expenses. With limited scalability, the system was unable to support the data needs of a rapidly evolving financial market.

Tight Exit Timelines

Bound by TSA (Transition Service Agreement) deadlines, the organization had little time to re-platform. Missing these timelines risked significant operational disruption.

Inability to Support Digital Banking Use Cases

Traditional banking models were no longer sufficient. The enterprise needed a platform capable of supporting advanced analytics, digital innovation, and next-generation services—but its outdated infrastructure posed serious limitations.

The Solution

To address these challenges, LTIMindtree designed and executed a re-platforming program built on Snowflake’s modern data architecture. Key aspects of the solution included:

• Smart Lift & Shift Migration: Leveraging the proprietary PolarSled accelerator, the enterprise migrated from Teradata to Snowflake in just 10 months.

• Automation at Scale: 60% of migration tasks were automated, eliminating manual intervention and reducing risk.

• Seamless Data Reconciliation: Automated reconciliation of both metadata and data across platforms ensured accuracy and continuity.

• Landscape Assessment: A tool-led assessment identified risks, complexity, and technical debt early, ensuring a well-structured migration strategy.

• Cloud-Native Architecture: Snowflake’s pay-as-you-go pricing, auto-scaling, and advanced data-sharing features positioned the organization for long-term success.

The Business Impact

The transformation delivered results that went far beyond cost savings:

• €3 Million in Cost Reduction: The move to a modern, efficient data platform directly reduced operational expenses.

• 50+ TB of Data Migrated: Large volumes were securely migrated and reconciled, ensuring no compromise on critical data.

• Future-Ready Platform: With Snowflake’s SaaS architecture, the enterprise can now seamlessly adopt digital banking innovations and scale as demands grow.

Why It Matters

This case demonstrates the power of aligning technology modernization with business imperatives. By combining Snowflake’s cloud-native flexibility with LTIMindtree’s proven migration accelerators, the financial services group unlocked significant savings while ensuring scalability and innovation readiness.

But the real value lies in what’s next: how this platform empowers the client to embrace new use cases in digital banking, analytics, and customer experience transformation.
