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.

Adoption success. New voice solution for a media company

Moving to a unified communications platform to accelerate digital transformation and boost productivity.

Overview
Technology is changing the world as we know it.
It’s a huge challenge for organisations looking to accelerate their digital transformation. Including one of our longstanding customers, a mass media company who needed to move to a unified communications platform to help their teams work smarter and improve customer and user experience. But when you’re a global organisation with 30,000 staff across 170 locations in 84 countries, it’s not so straightforward.

The challenge
Changing user behaviour
The rise in remote working meant a number of their employees were using their own phones, laptops and unsupported collaboration apps. Lack of visibility and control of BYOD not only posed a real risk to their network, but also user experience.

Having everyone use a single solution across chat, phone and meetings would not only simplify end user experience but improve collaboration, increase productivity, and strengthen security. But due to their size, this wouldn’t be an easy task.

It wasn’t just about rolling out a new communications platform across the organisation but changing its culture too. The customer needed to educate its people before, after and during the migration to ensure they fully embraced the new technology and got the most out of it.

And that’s where our user adoption service came in.

In addition to adding great business value, the BT user adoption team worked as collaborative partners and were a true pleasure to work with.”

The solution
User adoption made simple
The customer was using multiple collaboration tools – this wasn’t cost-effective or scalable. Migrating to Microsoft Teams Direct Routing would give them a workspace for real-time collaboration, communication and meetings, all in one place. Along with a choice of calling plans over our global SIP network allowing them to make and receive calls within the platform.

Our proven methodology has helped organisations achieve faster business results and ongoing value from their cloud technology investment. So, we were best placed to deliver a user adoption programme to support the upgrade of 27,000 users to the new cloud-based platform.

A big part of our user adoption service is taking the time to understand our customers’ business challenges. Our dedicated specialist spent time with them to understand their users’ current behaviour and identify the change required.

The plan was to deliver an “early adopter” programme to 420 employees. The customer would then take the learnings from the programme to further improve the overall roll out of Microsoft Teams Direct Routing to its wider organisation.

To support the early adopters through the change and drive engagement, we created a detailed launch communication plan, including training and assets, and personalised email communications inviting them to attend tailored online training sessions. We also launched a user content library for online video tutorials, quick start guides and FAQs. We created additional help and advice for hearing impaired users, guiding them through the platform's accessibility features, like live captions. Users were asked to complete a small survey four weeks after the early adopter launch, to provide valuable insight to help improve the wider roll out.

In addition to our comprehensive early adoption programme, we also set up our Genius Desk, a ‘go to’ specialist team who became a part of the customer’s organisation for six months. The team offered users specific help and support on each phase of the Teams migration to drive maximum adoption.

The result
A better user experience
We successfully helped the customer change user behaviour and get everyone on board. The early adopters programme achieved 100% take-up as a result of our detailed launch plan - avoiding any disruption to business activity.

Our user adoption team received high praise from the customer, calling out their amazing support for what was “a very complex series of inter-related projects” and how they were a “true pleasure to work with”.

Users also got a lot from our training, with one saying: “It was fast paced, insightful, and will help me be more efficient day-to-day.”

Six months since the roll out of Teams the customer has seen call volumes increase 15 times over.

The training was fast paced, insightful, and will help me be more efficient day-to-day.”
