In today’s enterprise landscape, mergers and acquisitions often result in fragmented digital ecosystems—multiple cloud tenants, duplicated intranet portals, and siloed data. This was the exact challenge facing Naviam Group, a global leader in enterprise asset management (EAM), operating through several subsidiaries including: BPD Zenith, Peacock Engineering, EAM Swiss, Projetech, Interpro, Active G, Sharptree, ZNAPZ, and Lexco.

Over time, each company had developed and maintained its own separate Microsoft 365 and SharePoint tenant, leading to significant operational inefficiencies, inconsistent user experiences, and mounting IT overhead.

That’s where Stark Systems came in.

The Challenge

Naviam Group’s leadership wanted to:

• Consolidate all nine SharePoint tenants into a single, unified tenant
• Merge and streamline department intranet portals, which had grown redundant across business units
• Improve data governance, security, and cross-company collaboration
• Maintain business continuity throughout the transition

This required not only advanced technical expertise in SharePoint migrations but also careful change management to unify global teams under one digital workplace.

The Solution

Stark Systems developed and executed a phased migration strategy over 6 months, ensuring a seamless and secure transition across all business entities. Our approach included:

🔹 Phase 1: Strategic Discovery & Mapping

• Conducted a full audit of each tenant’s structure, usage, and content lifecycle
• Identified redundant, outdated, or duplicated intranet portals and libraries
• Designed a unified information architecture to support all business units under one SharePoint framework

🔹 Phase 2: Unified SharePoint Tenant Migration

• Created a centralized Microsoft 365 tenant with role-based access and compliance configuration
• Migrated over 40 TB of content from 9 tenants using a mix of automation tools and custom scripting
• Implemented Azure AD B2B guest access during transition phases for external collaborators

🔹 Phase 3: Intranet Portal Consolidation

• Streamlined more than 30 departmental intranet sites into a single modern digital workplace
• Used SharePoint Hub Sites to organize content by function (HR, Ops, Finance, etc.)
• Embedded Microsoft Teams and Power Platform integrations for real-time collaboration

🔹 Phase 4: Communication & Adoption

• Delivered stakeholder workshops and global training sessions
• Developed a “What’s Changing?” campaign to support adoption across teams
• Established post-migration governance framework with Naviam’s central IT

🚀 The Results

The impact of the project was immediate and measurable:

Metric	Before	After Migration
SharePoint tenants	9	1
Department portals	30+ (redundant)	1 portal with 6 hubs
Average file search time	~2–3 minutes	< 10 seconds
User adoption	—	96% in first 30 days
IT overhead (hours/month)	~120	~40

The unified system significantly reduced operational overhead, improved compliance, and created a cohesive digital experience for over 1,800 employees across 12 countries.

💬 “We finally feel like one company—Stark Systems helped us make that a reality, not just on paper, but in the tools we use every day.”
— Group CIO, Naviam Group

What’s Next

Stark Systems is now supporting Naviam Group in rolling out Power BI dashboards, Power Automate workflows, and employee onboarding automation within the consolidated tenant—maximizing ROI on Microsoft 365 investments.
