LHV Bank and Tuum Reveal Blueprint for Seamless Core Banking Migration

Quick Summary

LHV Bank successfully executed a core banking migration using Tuum’s cloud-native platform to modernize its UK operations. By following a smart migration blueprint, the bank transitioned complex loan portfolios and payment systems without downtime, enabling rapid product innovation and scalable growth for its SME lending business.

How Does the Smart Migration Blueprint Solve Legacy Banking Issues?

The core banking migration process addresses the primary pain point for established banks: the risk of systemic downtime during upgrades. LHV Bank utilized Tuum’s modular architecture to decouple services, allowing for a phased transition rather than a high-risk "big bang" approach. This strategy ensured that critical payment flows and customer data remained accessible throughout the transition.

• Elimination of legacy technical debt.

• Seamless data integrity maintenance during transfer.

• Support for multi-currency accounts and real-time processing.

What Results Has Tuum’s Technology Delivered for LHV Bank?

By implementing Tuum’s platform, LHV Bank achieved a significant reduction in time-to-market for new financial products. The bank can now deploy automated lending workflows and integrated API services for its fintech clients with enhanced operational efficiency. The migration has specifically empowered LHV to handle increased transaction volumes within the UK’s competitive SME sector.

• Zero downtime during the migration window.

• Full cloud-native scalability for UK operations.

• Improved regulatory reporting accuracy via centralized data.

Why is Cloud-Native Infrastructure Critical for Modern Banking?

LHV Bank’s shift to a cloud-native core allows for elastic scaling, meaning the bank only pays for the computing power it uses while remaining ready for sudden spikes in digital transaction demand. This flexibility is a cornerstone of the core banking migration strategy, moving away from rigid on-premise servers toward a future-proof ecosystem that supports open banking and third-party integrations.
