CPS 230/234 Ready

Your core.
Your choice.
Your future.
Community and challenger banks face a binary question: keep the core you have and wrap it with modern capability, or transform to a modern core built for the digital era. Moroku works both ways — and we'll help you decide which is right for you.
The strategic question
What do we do with our core?
Wrap It
Keep your core. Add a modern API & ops layer on top.
Transform It
Migrate progressively to a modern core with our partners.

The Burning Platform
Staying put is no longer safe.
The calculus has changed. The risk of inaction now exceeds the risk of modernisation — and the window to act is narrowing for community and challenger banks.
APRA CPS 230 is live
Operational resilience requirements under CPS 230 and the expanding CDR mandate mean the compliance cost of running legacy infrastructure is rising — fast. Legacy platforms built for batch processing and overnight reconciliation were not designed for this world.
Majors are accelerating
The big four are deploying AI at scale, launching embedded finance products, and widening the experience gap. Every quarter a community or challenger bank delays modernisation is a quarter of competitive ground ceded — on customer experience, product speed, and margin.
Vendor lock-in is a trap
Many institutions are paying eight-figure licence fees for systems that can't support real-time payments, modern APIs, or cloud-native deployment. Vendor leverage is at its peak. The institutions that move now — incrementally and deliberately — will own the next decade.

Your Decision Framework
Two paths forward. One partner.
The right answer depends on your APIs, your appetite for change, your capital, and your strategic horizon. Moroku can guide and deliver both.
A
Wrap the Core
Keep it. Connect it.
Extend it.
Extend it.
If your core banking system has functional APIs and you want to preserve it —
or you're not yet ready to migrate — wrapping is the fastest path to
modern capability. Moroku sits above your core as a digital abstraction layer,
delivering modern banking operations, customer engagement, and digital channels
without touching the ledger.

Transform the Core
Move to a core
built for today.
built for today.
When your existing core can't support the products, real-time capabilities,
or API connectivity you need — or the cost of maintaining it has become
unsustainable — it's time to transform. Moroku partners with Mambu,
Thought Machine, and Fiserv to deliver modern core migrations that are
incremental, de-risked, and structured around your growth strategy.

From the Legacy Trap Paper
Three proven migration pathways
Every institution's circumstances are different. The paper details three approaches — each with distinct risk profiles, timelines, and capital requirements.
C
Digital Abstraction Layer
Reduce vendor dependency and modernise the customer experience immediately, while preserving full timing flexibility on the core migration itself.
3–6 mo
Time to value
Low
Capital required
Ideal for
Institutions with high vendor risk and limited capital, or those wanting to prove the business case before a full migration commitment.
Wrap-first strategy
A
Open Banking-Led Migration
Use CDR compliance as the integration architecture between legacy and modern systems. Build the data and API foundation, then migrate capability progressively behind it.
6–12 mo
Time to value
Medium
Capital required
Ideal for
Institutions with strong digital channels but weak core integration, where CDR compliance is already a mandate and can fund the transformation.
CDR as the catalyst
B
Greenfield Parallel Migration
Launch new business on a modern core stack while migrating the existing customer base progressively. De-risks the migration and funds the programme through new product revenue.
4–6 mo
First value
Higher
Capital required
Ideal for
Growth-focused banks needing new products that legacy simply can't support — credit cards, BNPL, embedded finance — and a board willing to commit to transformation.

What Moroku Brings
Strategy, delivery, and the platform.
We're not just a software vendor. We sit alongside your leadership team from the first strategic conversation to go-live and beyond.
Capability Completeness Audit
Before choosing a path, we map every operational function, score migration complexity, and identify gaps that could derail a programme. The audit de-risks the decision and builds the business case for your board.
On-Ramp Design Sprint
A structured 6-phase sprint to define your unique digital banking experience, validate with real customers, and produce a functional prototype — before a dollar is committed to core migration. Strategy becomes something you can see and test.
Integration Services
Moroku's integration layer connects your core — old or new — to digital banking channels, open banking APIs, and the full Bank Ops platform. Pre-built connectors for Mambu, Thought Machine, and Fiserv reduce integration effort to weeks, not months.
Bank Ops — The Operating Platform
Whether you wrap or transform, your team needs a modern operating platform. Bank Ops delivers unified customer management, KYC, lending, compliance, and financials — in one place, connected to whichever core is underneath. It moves with you.
