Beyond the Legacy Trap
A strategic framework for core banking modernisation. Discover why Australian challenger banks, community banks, and non-bank lenders must move beyond legacy platforms—and how to do it without betting the institution.
Key Insights from the Paper
Challenge the prevailing orthodoxy that migration from legacy core banking systems is prohibitively risky.
Staying Put Is Now the Riskiest Option
Legacy platforms were architected for batch processing and overnight reconciliation. With APRA's CPS 230 requirements and CDR expansion, the risk profile of staying has become greater than the risk of modernising.
What Failed Migrations Actually Teach Us
Most failures came from big-bang approaches, customisation overreach, and capability completeness failures. The market has changed—migration is no longer a single event but a capability that can be built incrementally.
Three Proven Migration Pathways
Each pathway suits different institutional circumstances, risk appetites, and strategic objectives. From Open Banking-led migration to Digital Abstraction Layers, there's an approach that fits.
The Capability Completeness Framework
Before any pathway decision, a comprehensive capability audit de-risks the journey. Map every function, identify gaps, and score migration complexity to make informed choices.
Three Migration Pathways Explored
The paper details three distinct approaches to modernisation, each with different risk profiles, timelines, and capital requirements.
Open Banking-Led Migration
Leverage CDR compliance as the integration layer between legacy and modern systems. Ideal for institutions with strong digital channels but weak core integration.
6-12 months to valueGreenfield Parallel Migration
New business on modern stack while migrating existing progressively. Best for growth strategies requiring new products that legacy can't support.
4-6 months to valueDigital Abstraction Layer
Reduce vendor dependency immediately while preserving timing flexibility. Optimal for institutions with high vendor risk and limited capital.
