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.

State of the art SAP Migration at Liège Airport

Contrary to what one would expect, the implementation of ERP does not necessarily have to be long and tedious. Hardly four months have passed since its implementation with Liege Airport showing that renewing software does not need to be a long-lasting operation. The airport opted for an All-in-One SAP solution and awarded the assignment to NRB.

“We wanted above all to improve our commercial and accounting procedures. The airport has, moreover, other projects where this new software can be used”, says Willy Delflys, Secretary General of Liege Airport.

Due to the growth of the airport and the expansion of its activities, Liege Airport has been confronted with a certain number of limitations with regard to its accounting software. It should also be noted that after ten years, this support had become practically non-existent. In addition, the management application for purchasing, developed internally ten years ago, was no longer suitable for today’s working world. The operation involving purchases and accounting was no longer adequate.

New ERP synonymous with time saving

“When a purchasing request is introduced in SAP All-in-One, the software automatically activates accounting charges in the accounting module”, explains Willy Delflys. “In the past, this operation had to be carried out manually with the risk of error linked to data capture. This integration reduces the problems linked to errors and enables considerable time saving. As a result, the productivity of our employees has increased considerably”.

It is precisely for these numerous integration possibilities that Liege Airport opted for a SAP solution. “The management of this procedure by SAP was in every respect considerably more important than its look and user-friendliness”, adds Willy Delflys. “Purchasing was also part of a long-term vision. We started with the two modules mentioned but were able to extend the scope of the solution without any problem. We are now planning in the short term to adopt a real estate management module as the application currently in use is also ten years old. We are also working with isolated applications for personnel and customer management and it is for this reason that we are also examining the possibilities offered by SAP HCM and SAP CRM. In this context, we are following the recommendations of NRB and SAP who have extensive experience in the airport sector”.

Rapid migration thanks to SAP’s excellence practices

Migration to the new system was carried out seamlessly because Liege Airport agreed to follow the excellence practices used by SAP. NRB then only needed 250 working days to implement the system, a real record! Willy Delflys adds: “Our procedures closely resembled the approach that SAP recommends. We therefore had no difficulty in following the recommended best practices. This enabled us to carry out migration in a sufficiently short time, even if SAP All-in-One was more or less already preconfigured. The extra work for our teams, which included a key user by the department concerned and a project manager, was on the whole kept to a minimum. We decided to limit this period as much as possible because we were afraid that the staff of the departments concerned would after a while loose all motivation”.

Willy Delflys did not hesitate a single second to assign this operation to NRB. “This company has an excellent reputation and is situated nearby. This nearness is a nonnegotiable asset for a migration of this type. Now that the system has been set up, I can confirm that the professionalism shown by NRB in managing this project impressed us greatly. Their consultants have exceptional know-how”.
