Banking Modernization Practice
Why Banking Modernization matters.
The Real Challenge
Most banking modernization programs are approved as one project and delivered as many. A core system replacement, for example, pulls in the digital channels sitting on top of it, the payments integrations running through it, and the data that has to move and reconcile before any of it goes live. Institutions that budget for one stream and treat the other three as downstream detail find the cost of that assumption along the way through change control or only after go-live.
Sometimes the trigger is not a decision at all. Central 1 announced in October 2024 that it would wind down its digital banking business, and in early 2025 the Forge and MemberDirect platforms, along with the teams running them, transferred to Intellect Design Arena. The digital banking operations of more than 170 Canadian credit unions and banks moved with them, and those institutions are now working through a digital platform transition none of them chose the timing of. That is a channel program, not a core program, and it lands on the same teams and the same budget cycle as everything else.
The rest of the agenda is arriving on published dates. KPMG in Canada reports that 93% of Canadian financial institutions have a payments modernization program planned or already underway, at an average expected investment for the larger institutions of $19.4 million each. This tracks with the US market, where a Jack Henry & Associates survey found 76% of financial institutions planning to increase technology spending. The Real-Time Rail by-law came into force in August 2026 with production launch to follow, and American institutions are already running FedNow and RTP alongside their existing rails.
The failure mode is rarely the technology. It is a business case that was never plausible, a scope that left out the systems around the core, and a governance structure that could not reach a decision fast enough to matter. A $20 million program sold on a three-year return should raise questions before it raises a purchase order.
How We Help
The 2Oaks Banking Modernization Practice helps financial institutions plan and deliver change across the whole banking estate under one team: core systems, digital channels, payments, data, open banking readiness, and the products configured on top of them. We work with Canadian and American banks and credit unions that are carrying a program of this size without a large internal technology group to absorb it. Our consultants have run this work from inside financial institutions, and our advice carries no vendor incentive.
Whether you are testing if a platform replacement is justified at all, choosing a platform, sequencing a migration, preparing for new payment rails, or stabilizing a system that went live before it was ready, our work is built to hold up on the day it matters.
From Platform Decision
To Stable Operation
Our consultants deliver the full scope of work required to take a banking modernization program from the first platform question through to steady-state operation:
Core. Platform selection that starts with an honest replacement rationale, a migration strategy chosen against your operating model rather than the vendor's delivery calendar, and cutover approaches weighed on what your institution can absorb
Digital. Retail and business digital banking migration, with requirements ownership and vendor coordination supplied where your team is already carrying a day job, including the public website that almost always has to change with the platform
Data. The extraction, transformation, and reconciliation work that platform vendors do not supply, and the reporting that regulators and your own management depend on once the old system is gone
Payments Modernization. Payments and card program delivery across multiple providers, with clearing, settlement, and certification treated as early program requirements rather than late discoveries, in a market where Canada is standing up the Real-Time Rail and US institutions are already operating FedNow and RTP in parallel
Open Banking. Readiness in the layers that decide whether you can move when the rules land: how customer data is held, how access is controlled, and whether your platform can expose it safely. Timing is unsettled in both markets, and the architecture work holds its value either way
Products. Product configuration in the new platform, on the principle that a long list of core customizations is evidence the system does not fit rather than a workstream to staff
Governance and delivery. Steering committee, change advisory board, and architecture review board structures that let a program touching four systems at once decide at the speed the timeline requires
Readiness, cutover, and stabilization. Data mocks, dress rehearsals, runbooks, and a plan for the months after go-live, on the understanding that go-live is the middle of the program rather than the end
Our Point of View:
The Practice is built around six positions we hold consistently across every engagement:
Modernization Is a Program, Not a Project. Core, channels, payments, and data arrive together because the same aging technology triggers all of them. We sequence them deliberately, and we would rather have the argument about sequence at the start than watch three streams collide in the same quarter.
The Business Case Has to Be Plausible. We will say so when a payback period does not survive scrutiny. A $20 million program sold on a three-year return is a business case problem before it becomes a delivery problem, and it costs far less to raise during selection than during hypercare.
Configure Rather Than Rebuild. Modern platforms are configured, not extended. When a program starts generating a long list of core developments, that is evidence the selected system does not fit, or that requirements are being used to rebuild the old system inside the new one.
Ancillary Systems Decide the Timeline. The core is the smaller part of the problem. Payment gateways, CRM, loan origination, and financial crime monitoring tools are where integration effort concentrates, so we scope them at the start and attach a 20 to 30 percent contingency to that work rather than absorbing it later
Vendor-Neutral Advice. We hold no preferred-vendor arrangements, which is what keeps the advice impartial. We do have relationships across the major platform vendors, and that is what lets us compare them: our consultants have led core implementations and upgrades on Temenos and Finacle, core design and automation on Technisys, and channel and integration work around Temenos Infinity, WealthView banking / Ovation, and Fiserv DNA. We also negotiate project-phase terms into contracts that vendors usually write for steady-state operation only.
Capability Transfer, Not Dependency. We work alongside your team and hand over as we go. Implementation partner warranty periods typically run about 30 days while stabilization runs from three months to a year, so we plan for that gap and leave your team operating the platform rather than depending on us to.

Partner with 2Oaks to modernize your banking platform as one program, with a business case that holds up, a scope that includes the systems around the core, and a team that hands the result back to you.
How is this different from replacing our core banking system?
A core replacement is usually what triggers the work and it is the largest single piece, but it is not the whole program. The channels your customers use, the payments running through the institution, the data that has to reconcile, and the products configured in the new platform all change at the same time and depend on each other.
We scope and sequence them together rather than treating three of them as consequences of the fourth.
Two articles cover the core decisions in depth: Before You Begin: What Every Bank Needs to Know Before Replacing Its Core System and How to Select a Core Banking System.
What governance does a program this wide actually need?
Three groups. A steering committee for direction and escalation, a change advisory board to control scope, and an architecture review board to hold technical decisions to the target state.
The structure that works at the start of a program is not the structure that works at cutover. Early governance is weighted toward architecture and system decisions, then toward testing and defect resolution, then toward operational readiness and the transition to business as usual. Planning that shift is part of the work.
Our article sets out how that evolves: Banking System Implementation Governance.
We are being told we need to be ready for new payment rails and for open banking. How much of that is real?
The payments half is real and dated. In Canada the Real-Time Rail by-law came into force in August 2026 with production launch following and Interac e-Transfer clearing and settlement migrating through 2027. In the US, FedNow and RTP are already live, so American institutions are running parallel rails today. KPMG in Canada reports 93% of Canadian financial institutions have a payments modernization program planned or underway.
Open banking is less settled in both markets. Canada's consumer-driven banking framework is still being stood up, and in the US the CFPB's Section 1033 rule was finalized in October 2024, then enjoined in late 2025 and reopened for reconsideration. Our advice is to treat the rules as uncertain and the architecture as not: data access controls, customer data structure, and the ability to expose it safely are worth building either way, and they are the same foundations your payments and reporting work needs.
On delivery, payments programs are coordination problems before they are technical ones, and certification is the requirement most often discovered late. For FirstOntario Credit Union, a $7.9 billion credit union in southern Ontario, we coordinated five external providers through a single program management layer to launch a debit Mastercard with fraud monitoring, delivered on time and on budget.

We are mid-migration. Does our continuity plan still cover us?
What happens to our data during a migration?
Your Questions Answered:
More of it falls to you than most institutions expect. Platform vendors generally supply data upload tools but not the extraction, transformation, or reconciliation routines, and reconciliation has to prove the new system balances to the source before anyone signs off on cutover.
Reporting is the usual casualty, because it feeds consumers nobody lists in the original scope, including the regulatory returns you file to OSFI in Canada or to the NCUA and federal banking agencies in the US, and the financial crime reporting that goes to FINTRAC or FinCEN. We plan a 20 to 30 percent contingency for ancillary and integration work for the same reason.
For what surfaces late, see The Hidden Risks of Ancillary Systems in Core Banking Transformation and our Data Migration service.
Probably not, and supervisors are less forgiving about this than they used to be. In Canada, full adherence to OSFI Guideline E-21 took effect on September 1, 2026, and the guideline does not pause for a major program. In the US, the FFIEC Business Continuity Management booklet sets comparable expectations for banks and credit unions, NCUA examiners assess it directly at federally insured credit unions, and the largest institutions also fall under the interagency sound practices for operational resilience.
Three things are usually missing: a continuity plan that reflects the period when you are running partly on each system, a rollback plan that has been tested rather than written, and a clear answer to who has authority to invoke it in the middle of a hypercare weekend.
