Cardo Group Merges SERS Into Cardo's IT Systems
Cardo Group Ltd appointed Nexus to support and deliver the successful migration of the SERS business, following its acquisition. This complex programme required a comprehensive assessment of the existing IT estate, strategic planning, and careful execution across multiple locations including Wales, England and Scotland.
The migration achieved a seamless transition of infrastructure, systems, data, and user services onto Cardo’s technology ecosystem. All outcomes focused on business continuity, cybersecurity, and employee experience.
The Goals
The SERS acquisition required the full integration of all existing IT infrastructure, applications, data, and security processes into the Cardo environment. The legacy SERS environment supported multiple distributed teams and third-party systems, meaning that full visibility of every component was vital to ensure a smooth cutover, minimal downtime, and robust risk mitigation.
Cardo required:
- A complete technology estate inventory
- Clear mapping of users, systems, data, and dependencies Network and security assessment
- Migration of services and workloads
- Standardisation of access, authentication, and compliance
- Continuity planning covering remote, field, and office-based workers
Assessment and Implementation
Nexus delivered an end-to-end migration programme designed to fully integrate SERS into the Cardo Group environment with zero business disruption.
1
From day one, we worked closely with Cardo to ensure the newly acquired SERS team felt informed, supported, and confident about the change. We assisted in managing the opening communications to all affected employees, reassuring them that their systems, data, and day-to-day tools would remain protected, and that Nexus would be on hand to look after them throughout the transition. This early engagement established trust and created a smooth foundation for onboarding.

We then carried out a deep-dive assessment of the inherited IT estate, documenting all hardware, software, network infrastructure, cloud services, and security practices across the locations of the acquired business. This gave Cardo complete visibility of assets, configurations, and dependencies, and ensured plans were grounded in a detailed understanding of how each site operated.

Nexus standardised authentication and access controls, aligned systems with Cardo’s existing security model, and completed data mapping to understand where business information lived and how it flowed. Telephony, printers, meeting room technologies, and user services were brought into scope to maintain continuity for office, field, and remote workers.
4
Network routing, internet services, firewalls, and wireless infrastructure were reviewed and documented, ensuring connectivity remained secure and resilient. All third-party applications, contracts, and licences were assessed for compliance and successful transfer.
5
Finally, continuity and backup plans were validated to safeguard critical data post-migration. Azure and Microsoft 365 environments were reviewed for cost optimisation and licence efficiency, giving Cardo the clarity needed to manage and evolve their new environment.
Assessment and Implementation
The migration provided Cardo with complete visibility and control of the acquired IT estate, enabling proactive decision-making and strategic alignment with the wider business.
Cardo recognised the smooth collaboration and quality of delivery, providing highly positive feedback.
Key achievements:
- Successful migration completed on time and within scope
- Completely avoided major operational disruption
- Standardisation of security, access control, and identity management
- Clear documentation of all third-party systems, licences, and dependencies
