Moving Legacy Systems to the Cloud Efficiently : Balancing cost, risk, and continuity in complex migrations

Migrating legacy systems to the cloud remains one of the toughest balancing acts in IT. Every choice affects stability, cost, and trust at once, and what starts as a modernisation effort quickly turns into a negotiation between ambition and reality. Suddenly budgets rise, dependencies appear late, and timelines tighten as old architectures collide with new expectations. In the end, success depends on sequencing, ownership, and aligning business priorities with infrastructure limits, and not only on technical readiness. Making it work requires more than a plan on paper. Knowing which systems genuinely belong in the cloud, which can wait, and which should stay put shapes the entire roadmap and defines its success. Each refactoring decision sets the level of future flexibility, but it also drives cost and risk. The trade-offs between speed, sustainability, and resilience only become clear once migration begins and pressure builds. Let’s discuss how to plan migrations that stay on track, manage hidden dependencies, and handle downtime with confidence. Let’s also discuss how governance, testing, and vendor coordination keep progress visible and credible. Are you in? A closed conversation for those who turn cloud migration from a disruption into a long-term advantage.

The CIO as Investor - CIONET Belgium Annual Event

CIOs today are being judged less as technology leaders and more as portfolio managers. Every euro is under scrutiny. Boards and CFOs demand lower run costs, higher efficiency, and clear ROI from every digital initiative. Yet, they also expect CIOs to place bets on disruptive technologies that will keep the enterprise competitive in five years. This constant tension is redefining the role. In this session, we go beyond FinOps and cost reporting to tackle the strategic financial dilemmas CIOs face.

AI-Driven Development: Redesigning workflows, responsibilities, and trust in the age of automation

AI coding assistants entered development teams quietly, but their impact grows by the day. What started as autocomplete now shapes architecture decisions, documentation, and testing. And when productivity gains are visible, so are new risks: security blind spots, uneven quality, and the slow erosion of shared standards. Teams move faster, but not always in the same direction. The challenge has become integration rather than adoption. And new questions have risen: how do you blend automation into established practices without losing oversight? When is human review still essential, and what should the rules of collaboration between developer and machine look like? As AI tools learn from proprietary code, where do responsibility and accountability sit? Let’s talk about how to redefine those workflows, balancing creativity with control, and protecting code quality in a hybrid human-AI environment. A closed conversation on where AI accelerates progress, where it introduces new debt, and how development culture must evolve to stay credible.

Zero Trust in Reality : Making segmentation, identity, and access work in complex environments

Zero Trust sounds simple on paper: trust no one, verify everything. But once you start implementing it, the fun begins. Legacy systems, hybrid networks, and human habits don’t read the manual. The idea is solid; the execution, not so much.

Finance Company Will Build Native Mobile Apps with Low-Code Platform

CA CF NL Consumer Finance Nederland B.V. is a financial company that needed to revamp its outdated core banking system. Initially, they intended to create only a few applications with the OutSystems platform. However, they quickly realized how easy it was to replace existing systems and build new applications.

CA CF NL - Build Native Mobile Apps

Legacy System Modernization Creates a Competitive Advantage

Challenge - CA CF NL is part of Crédit Agricole Consumer Finance, a leading player in the European consumer credit market. With an outstanding portfolio of over 2.3 billion euros, CA CF NL is one of the largest finance companies.

CA CF NL is committed to digital transformation and, as part of that, the company wanted to update its legacy banking applications.

“CA CF NL is basically an IT company with a banking license,” says Erwin Kooiman, senior manager IT, who leads a team of IT specialists covering functional and technical maintenance. After analysing the challenge he faced, Kooiman realized he was going to need some help. That’s when he started looking at the OutSystems low-code platform.

"With OutSystems low-code development platform, we can build native mobile apps that will give us a huge competitive advantage and help us fulfil our goal of becoming a true digital financing partner."Erwin Kooiman, IT senior manager at Credit Agricole Consumer Finance (CA CF NL)

Low-code Platform an Ideal Integration Tool That Delivers Speed at Enterprise Scale

Solution - CA CF NL’s architects quickly concluded that OutSystems was the best option for them, recalls Kooiman. “In addition to being a good development platform, it fit well into our core systems, which made it ideal for integration.”

Kooiman adds, "Initially, we only wanted to develop a few non-critical systems ourselves but soon we decided to start developing mission-critical systems. We also bridged the gap between off-the-shelf solutions and tailored systems that make us unique.”

CA CF NL felt it was important to work closely with OutSystems and an integration partner on the legacy system modernization. "The core banking system and ESB are critical to our business, so the transition had to be done right in one go," Kooiman explains. "I was really pleased with the guidance we received, first from OutSystems in Portugal, and later from our Dutch implementation partner COOLProfs."

Another aspect of OutSystems that Kooiman and his team really liked is that it enables rapid interaction between developers as well as testers and users. That means that applications can be delivered and adapted quickly, increasing interaction with the business.

Applications built with OutSystems include:

Replacing interfaces and modules that were connected to the outdated core banking system.
Building an enterprise service bus (ESB) that would connect different platforms to the banking system.
Developing a product catalog application to manage CA CF NL’s financial products and reduce the complexity of maintaining products in the Core Bank environment.
Creating an application that allows customers to compare different financial offers and that functions as a contact platform between employees and clients. This took only 6 weeks to build and deploy.
Optimizing process flows and introducing process orchestration, allowing the core processes of the bank to become full STP (Straight Through Processing).

OutSystems Helps CA CF NL Become a Mobile Development Center of Excellence

Results - Kooiman and his team were pleasantly surprised by the ease and speed of building native mobile apps, and this led to the idea of becoming a Mobile Development Center of Excellence.
Kooiman couldn’t be happier with the way things are going. “Our IT team becomes a well-oiled machine running at full speed. With this new élan, we are convinced we will be able to maintain our position in the market and face the challenges of digitalization ahead.”

OutSystems enabled CA CF NL’s IT team to:

Build any kind of application they needed, fast and easy
Implement an agile development methodology
Rejuvenate the IT team and become a more attractive employer for young and savvy developers
