The Migration Factory

Secure Microsoft Tenant Mergers, Splits And User Migrations With Minimal Disruption

We Are Tenant and Domain Consolidation Experts

VTG runs a repeatable Microsoft tenant and identity Integration Factory for acquisitive groups helping organisations complete mergers, divestments and restructures securely and efficiently.

We start with an Active Directory assessment to baseline security, compliance and overall health, then execute tenant-to-tenant migrations across Exchange, OneDrive, SharePoint and Teams, plus server and application migrations across domains, with security and compliance aligned and minimal disruption.

Merging or separating Microsoft 365 or Azure tenants and Active Directory domains is one of the most complex and high‑risk changes an organisation can undertake. Identity, access, email, collaboration and applications must transition together, without impacting users or operations. 

The intricacies involved in these processes demand a high level of expertise and the ability to adapt to unique organisational needs.

Real‑World Experience Makes the Difference

The gap between theory and real‑world execution is often underestimated. In reality, environments are shaped by legacy decisions, operational constraints and human behaviour that theory alone does not cover.

Experience at scale closes this gap. Insights gained from multiple complex projects enable earlier risk identification, proactive challenge management and solutions that work in real conditions, delivering consistently better results.

No Time For Downtime - Tenant & Domain Split Case Tudy

“We have been utilising the services of the Velocity Technology Group for many years now, and most recently for a highly complex initiative we needed to achieve in a short time frame and a completely remote fashion.

VTG brought the consultation, professionalism, best of breed resource skills and great account management together to deliver successfully for us.”

Making The Impossible...Possible - Tenant & Domain Migration Case Study

“In many ways it felt like we were facing an oncoming train,” says Wilson. “Fortunately, thanks to Velocity Technology Group’s experience and knowledge, they did not agree.

The best part is that in less than six weeks, we managed to migrate more users to Office 365 than had been migrated over the previous 3 years!”

A Standardised Approach

The Migration Factory combines assessment, blueprinting, and controlled execution to deliver tenant and domain consolidation or separation. 

Faster time to value: repeatable discovery and wave planning shortens mobilisation and reduces time to synergy.

Lower delivery risk: standardised runbooks reduce surprises and improve predictability across integrations and carve outs.

Reduced disruption: controlled coexistence and wave based cutovers protect front line operations.

Stronger security posture: baselined identity, permissions hygiene, and governance improvements are embedded, not bolted on.

Consistent governance: a defined target tenant and identity model prevents tenant sprawl and inherited privilege creep.
