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.

Nurturing H.Essers' growth ambitions

Workday implementation gives the transport, warehousing and logistics giant a clear picture of HR worldwide and enables it to integrate acquisitions more effectively.

Aiming realistically high

Established in 1928 by Henri Essers, H.Essers has grown substantially over the years, via both autonomous growth and a number of strategic acquisitions. Its aim is to become THE global reference in its strategic markets, namely pharmaceuticals, chemicals, infrastructure and parts. H.Essers was responsible for the European distribution of the Pfizer COVID-19 vaccine in 2020/2021.

For the immediate future, the firm’s predominantly focusing on the European market. Today, it has more than 6,600 employees spread across 19 countries in Western and Eastern Europe.

One single HR truth

That spread can make it challenging to get a clear picture of its human resources (HR) footprint and assure it’s being managed in the most effective way. “To be able to continue to grow and achieve our ambitions, we really need one single HR database, one single HR reporting tool, as far as possible one single recruitment process and so on, rather than each location having its own payroll, procedures, time and attendance recording processes, etc.” explains Mike Dautzenberg, Chief Human Resources Officer, H.Essers. “With one tool, it’ll also be much easier to integrate acquisitions,” he adds, That’s especially true when it comes to different titles or roles.

“I feel that everytime we approach a new element within the system, PwC has an expert on it who can help guide us.”

Operating optimally from a people perspective

To give it that big picture of HR, H.Essers opted to implement Workday human capital management software. “For two years, we looked around the market to find the right solution. Our organisation’s very complex and we needed a tool that all our employees could use, from blue collar up, whenever and from wherever, and that would provide the benefits we were looking for. We decided that Workday would best suit our needs,” Mike Dautzenberg says.

With one single HR platform, H.Essers will also be able to standardise working practices and procedures in all locations in which it operates and be able to put a global HR strategy in place. To help it implement the platform, H.Essers opted to work with PwC.

Keeping it simple, staying on track

As to why H.Essers opted to work with PwC for this project, he notes, “PwC proved to be very down to earth. The PwC people demonstrate the same values as we have in H.Essers; they keep things simple and are very positive. They’re very entrepreneurial. They’re people we feel we can rely on. A plus point was that they’re based close to us and speak our language.” He went on to say that the two firms work together in partnership to find solutions; “we have a good, open relationship where communication is very clear. The team knows what’s important to us and we support each other in reaching our goals. They really go the extra mile to make sure we get where we want to be.”

In COVID-19 times, with physical meetings not possible, Mike Dautzenberg was impressed that they managed to keep the cooperation positive and implementation on track. “Despite PwC not being able to be on site as planned, the project progressed as planned, thanks to the good relationship we have and our ability to continue to cooperate, albeit remotely.”

Specialists in every domain

Workday covers many aspects of human capital management and Mike Dautzenberg is impressed that PwC can offer a specialist on each topic: “I feel that everytime we approach a new element within the system, PwC has an expert on it who can help guide us on that specific area. On top of which, the team stays on top of deadlines and makes sure we make decisions that respect those deadlines.” That includes dealing with and helping resolve issues with third-party suppliers.

Calling on glocal skills

PwC’s global network also comes into play. One of the important modules of Workday for H.Essers is learning and development (L&D) as the firm needs to be able to track and report on required certifications. The PwC Network has already implemented the Workday L&D module for many clients and the Belgian team didn’t hesitate to reach out for support. “That we were able to call on global support, tailored to our own specific situation was invaluable,” Mike Dautzenberg says. And he goes on, “Workday gives our managers the insights into their people that they need to grow and develop their talent pools. Before, this was more based on instinct. With Workday, we’ve hard data to back it up.”

To date, PwC has helped H.Essers implement Workday for all master data of its core HR and L&D activities. “This was a massive challenge. At the beginning, much of the data to be input was either incomplete or out of date,” Mike Dautzenberg recalls.

Leveraging an ongoing partnership

With phase one complete, phase two involves the introduction of time and attendance recording, absence management, talent and performance management, recruitment, advanced compensation and expenses and more. Again, the module will go live in all countries at the same time.

But Mike Dautzenberg doesn’t expect the relationship with PwC to end there: “We plan to continue to grow via acquisition, which means continually introducing new people and teams to Workday. We expect PwC to be by our side to show us how to do this effectively and to continue to keep us up to date with evolutions to make sure we’re always getting the best out of our investment. PwC’s proven to be a true partner that can support us when we’ve questions and concerns - they simply put us in touch with the experts that can help.”
