340+ institutions modernised globally
Legacy core banking systems are the single biggest barrier to financial institutions adopting AI — they're expensive to maintain, impossible to integrate with modern tools, and incapable of supporting the intelligence capabilities members increasingly expect. zung.ai Digital Engineering removes that barrier, globally.

Every modernisation service
your institution needs
From a full legacy system migration to a targeted API layer over an existing CBS, or a brand-new cloud-native build from scratch — zung.ai Digital Engineering designs and executes the exact transformation path that's right for your institution, your timeline, and your budget.
Legacy CBS Migration
Full migration from any existing core banking system to the zung.ai AI-native fabric — data audit, schema mapping, parallel run, phased cutover, and post-migration support. Migrated institutions gain 18 AI agents, 300+ API integrations, and 99.99% cloud uptime from day one, with zero data loss and zero member disruption globally.
Zero Downtime · Global
API Modernisation Layer
For institutions that can't replace their CBS immediately — we build a modern open-banking API layer on top of your existing system, unlocking AI capabilities, mobile banking, third-party integrations, and real-time data access without touching the legacy core. Your new surface while your old engine still runs.
API-First · Non-Disruptive
Cloud Infrastructure Migration
Move on-premise infrastructure to cloud without disrupting operations — designing the target architecture, executing lift-and-shift or cloud-native re-architecture, optimising costs, and ensuring the new environment meets the security, compliance, and availability requirements of financial services regulators globally.
Cloud-Native · Compliant
Greenfield Digital Bank Build
For institutions launching new digital banking entities from scratch — we design and build the entire technology stack: cloud infrastructure, AI-native core banking, mobile app, USSD, API gateway, and compliance automation — delivering a fully operational digital bank in 10–14 weeks globally, ready for regulatory submission.
10–14 Weeks · Full Stack
Data Architecture & AI Readiness
Institutions with data locked in siloed, poorly structured legacy databases cannot benefit from AI. We audit, restructure, and unify your data architecture — building the data foundation required for AI models to train, retrain, and improve — transforming data debt into AI-ready data capital globally.
AI-Ready Data
Integration & Ecosystem Engineering
Build and maintain the integration layer connecting your core banking system to payment rails, mobile money networks, credit bureaux, regtech platforms, and partner fintechs — with 300+ pre-built connectors and a team that builds custom integrations to any financial infrastructure globally within weeks.

The migration process
From legacy to AI-native
without a single hour of downtime
01
Discovery & Legacy Audit
We begin with a 5-day deep-dive assessment of your existing system — documenting every data structure, every custom workflow, every integration, and every regulatory obligation. The output is a complete migration blueprint with exact timeline, risk register, and cost model before a single line of code is written.
5-Day Assessment · Free02
Schema Mapping & Data Transformation
Our engineering team maps every table, every field, and every relationship in your legacy schema to the zung.ai data model — writing automated transformation scripts that handle data cleaning, de-duplication, and enrichment. Every transformation is tested with a 100% reconciliation check before any data moves to production.
100% Reconciliation03
Parallel Run & UAT
Both systems run simultaneously for 2–4 weeks — every transaction processed on legacy is mirrored on the new fabric and outputs compared automatically. Discrepancies surface immediately and are resolved before cutover. Your staff train on the new system while members never notice anything has changed.
Dual Run · Zero Risk04
Cutover, Hypercare & AI Activation
Cutover happens in a planned maintenance window — typically a Sunday night, under 4 hours. By Monday morning your institution is live on the AI-native fabric. Our team provides 90 days of hypercare support post-launch, while AI models begin learning your portfolio immediately to deliver their first insights within 48 hours.

Engagement models
The right migration path
for your institution
Not every institution needs the same approach. We design the modernisation path that matches your timeline, budget, risk appetite, and regulatory obligations — then execute it with precision. Three proven engagement models, globally delivered.
Full CBS Replacement
6–10 weeks · End-to-End
Complete migration from your existing core banking system to the zung.ai AI-native fabric — data, workflows, integrations, channels, and compliance frameworks all migrated with zero disruption. Best for institutions ready for full transformation who want all 18 AI agents and 99.99% cloud uptime from day one globally.
Full data migration — zero loss guarantee
All 18 AI agents activated
90-day hypercare post-launch
API Modernisation Layer
3–6 weeks · Non-Disruptive
Your legacy CBS stays in place — we build a modern open-banking API layer on top, unlocking AI capabilities, mobile banking apps, third-party fintech integrations, and real-time data access without touching the core. The fastest path to AI benefits for institutions with complex legacy systems or recent CBS investments globally.
Legacy system untouched
