The Challenge

For a midsized professional services firm with over 200 employees spread across three regional offices, the technology stack had become a growing liability. The Director of Technology described the environment as “a decade of patchwork upgrades held together with hope.” The firm relied on a hodgepodge of on-premises servers running legacy applications, with network storage that was constantly near capacity. Every Monday morning, the IT team fielded an average of a dozen tickets related to slow file access, application crashes, or VPN dropouts for remote workers.

Compliance was another urgent concern. The firm handled sensitive client data — contracts, financial records, and intellectual property — yet their security posture was dangerously outdated. Antivirus definitions were often weeks old, server patching was manual and inconsistent, and there was no centralized backup or disaster recovery plan. After a near-miss ransomware incident that encrypted a shared drive (thankfully, a test file), the leadership team realised they could no longer afford to run on “good enough” infrastructure. They needed a complete modernisation that would guarantee uptime, security, and scalability without requiring a massive internal IT team.

The Director of Technology knew that simply swapping out old hardware for new wouldn’t solve the underlying issues of siloed systems and manual processes. The firm needed a partner that could not only design a modern, cloud-first infrastructure but also handle the migration with minimal disruption to billable work. That’s when they engaged MS&VG.

Our Approach

MS&VG began with a deep-dive discovery phase. Our engineers mapped every server, application, and network dependency, interviewing department leads to understand critical workflows. We identified that the firm’s core practice-management application could run efficiently in a virtualised private cloud, while file-sharing and collaboration tools were better suited for a hybrid Microsoft 365 environment. The plan was deliberately phased to avoid downtime during peak engagement periods.

We first migrated the firm’s on-premises Active Directory and file servers to a secure cloud tenant, implementing Azure Active Directory with single sign-on and conditional access policies. Next, we virtualised the remaining on-premises servers into a hyperconverged infrastructure (HCI) cluster at a colocation facility, giving the firm the performance they needed without the capital expenditure of a full data-centre rebuild. To eliminate manual patching, we deployed an automated patch-management system with a change-control dashboard that the Director of Technology could monitor from a single pane of glass.

Cybersecurity was woven into every layer. MS&VG installed an AI-driven endpoint detection and response (EDR) solution across all devices, configured a zero-trust network architecture, and implemented a cloud-based backup solution with immutable snapshots tested weekly. We also automated the onboarding and offboarding process for employees, cutting provisioning time from two days to under an hour. The entire migration was completed over three weekends, with zero unplanned downtime during business hours.

The Results

  • 99.99% uptime for all critical systems in the first six months post-migration, compared to 97.2% before.
  • 45% reduction in IT operational costs, including a 60% decrease in help-desk tickets related to slow performance and access issues.
  • 3x faster employee onboarding, with automated user provisioning and role-based access control.
  • 100% compliance with client security audits due to centralised logging, immutability backups, and automatic patching.
  • 1.5 hours — the time to restore operations after a simulated ransomware test, down from two days under the old system.

The impact went beyond numbers. The Director of Technology reported that the firm’s consultants could now access files and applications from anywhere without VPN fuss, making remote and hybrid work seamless. The leadership team, once hesitant about cloud security, became confident enough to explore AI-driven automation for repetitive client reporting tasks. “We used to dread infrastructure conversations,” the Director of Technology noted. “Now IT is a strategic enabler — not a
