Modernising legacy VMware infrastructure at Killik & Co

Killik & Co, an independently owned UK wealth manager, delivers investment management and financial planning services to private clients globally. Its business-critical platforms including CRM, financial systems, market data processing, and client applications span two UK datacentres and demand consistently high performance and availability.

After more than 15 years on VMware-based infrastructure, Killik faced a combination of infrastructure and commercial pressures. Cisco HyperFlex was approaching end-of-life, while escalating VMware licensing costs and uncertainty following Broadcom’s acquisition introduced financial pressure and strategic risk.

To address these challenges, Killik partnered with Forfusion to design and deliver a migration to Nutanix Cloud Infrastructure (NCI), establishing a simplified, scalable, and future-ready platform aligned to long-term operational resilience.

Killik & Co needed to modernise its on-premises infrastructure across two datacentres without compromising availability, performance, or business continuity.

Its existing Cisco HyperFlex and VMware estate was approaching end-of-life, increasing operational risk and placing additional strain on a small internal IT team. At the same time, VMware licensing changes and cost increases following Broadcom’s acquisition accelerated the need for a strategic platform shift.

Key requirements included:

• Maintaining always-on availability for business-critical financial systems.
• Supporting high-volume overnight global market data processing.
• Reducing operational complexity and administrative overhead.
• Simplifying vendor and support model consolidation.
• Delivering a low-risk, minimally disruptive migration.
• Establishing a scalable foundation for growth and future Disaster Recovery (DR) capability.

Core workloads included SQL Server, MongoDB, Microsoft Dynamics CRM and internal financial platforms.

Killik engaged Forfusion to architect and deliver a modern infrastructure platform built on Nutanix, designed to reduce complexity, consolidate support, and improve operational resilience.

Using Forfusion's ADIOlogy® methodology, the engagement covered end-to-end delivery: design, implementation, migration planning, workload transition, and ongoing managed services support.

The solution comprised:

• Nutanix Cloud Infrastructure (NCI) deployed on Nutanix hardware.
• AHV hypervisor replacing VMware ESXi.
• Nutanix Move for structured workload migration.
• Consolidated vendor support model across compute and platform layers.
• Integration with Veeam for backup and recovery operations.
• Technical enablement and training for internal IT teams.
• Ongoing operational support via Forfusion's FusionCare® managed services.

Forfusion worked closely with Killik’s infrastructure team throughout delivery, supporting design validation, data centre deployment, and phased migration across both sites.

Migrations were carried out using Nutanix Move, enabling a controlled transition of Windows and Linux workloads with minimal service disruption and reduced operational risk.

“We now have cleaner, simpler systems with better visibility. Everything is easier to manage and faster to work with.”

Anthony Wood, Infrastructure and Network Manager, Killik & Co

The platform transition delivered immediate operational improvements and established a stronger long-term infrastructure foundation.

Key outcomes included:

• ~45-minute reduction in overnight market data processing cycles.
• Simplified infrastructure management with improved visibility and control.
• Reduced operational overhead through unified support and tooling.
• Lower exposure to escalating VMware licensing costs.
• Successful migration delivered with minimal end-user impact.
• Improved scalability and readiness for future DR expansion.

The resulting environment provides Killik with a streamlined, high-performance infrastructure platform that reduces day-to-day operational burden while improving resilience and responsiveness.

With Forfusion providing ongoing managed services support, Killik now operates with greater confidence in platform stability, scalability, and long-term sustainability.

“Forfusion managed the project end-to-end. Having a trusted partner who understood our environment made the transition significantly easier.”
