Authorisation switch modernisation from legacy BASE24 to the BASE24-EPS payments orchestration platform
BASE24 & BASE24-EPS Migration
End-to-end programme advisory for organisations migrating their card authorisation switching infrastructure from legacy BASE24 to BASE24-EPS — covering parameter migration, HSM key management, downstream interface re-mapping, and scheme certification.
Why It Matters
Migrating from BASE24 to BASE24-EPS is one of the most technically complex programmes a payments organisation can undertake. The parameter migration alone — IDF tables, product codes, routing logic — can take months to validate. Our consultants have delivered these programmes before and know exactly where the risk concentrates.
What We Deliver
- Current-state BASE24 environment assessment — transaction routing tables, IDF/TDF parameter sets, HSM key hierarchies, and downstream host interfaces
- BASE24-EPS target architecture design: authorisation engine configuration, BASE24-EPS product table migration, and payments orchestration layer design
- HSM integration planning — Thales payShield / Utimaco key ceremony procedures and key-block migration strategy
- Interface re-mapping: ISO 8583 message format translation, acquirer host connectivity, and network management message (NMM) redesign
- End-to-end test strategy: unit, integration, regression, performance (TPS benchmarking), and Visa/Mastercard scheme certification
- Cutover planning: parallel-run architecture, transaction replay validation, and rollback procedures with defined go/no-go criteria
- Post-migration hypercare: authorisation hit-rate monitoring, decline-reason analysis, and operational knowledge transfer

Our Approach
How We Engage
Assess First, Recommend Second
We invest time upfront to understand your authorisation platform, your parameter configuration, your downstream interfaces, and your constraints — before we recommend anything.
Embed and Deliver
Our consultants work alongside your programme teams — in your war rooms, on your test environments, in your scheme certification calls. We take accountability for outcomes, not just advice.
Transfer and Exit
Every engagement ends with your team more capable than when we arrived. We document, train, and hand over — building internal capability, not dependency on external consultants.
Not Sure Which Service You Need?
Tell us about your programme — whether it is a BASE24 migration, a compliance gap, or a platform investment decision — and we will help you work out the right approach.
