Tenant-to-Tenant Migration Streamlined Microsoft 365 Consolidation for a Global Electronics and Semiconductor Manufacturer

The Challenges

A global leader in electronic design and test solutions, maintains a robust Microsoft 365 infrastructure to support enterprise collaboration, data analytics, and cloud management.

It was to acquire a cybersecurity firm whose Microsoft 365 tenant was the source environment for this migration. The project aimed to integrate cybersecurity firm’s digital assets into the electronics company’s tenant to support operational continuity and centralized governance.

The company faced the following challenges:

• Complex Workload Migration: Included Exchange Online, SharePoint Online, OneDrive, Teams, Viva Engage, Power Automate, PowerApps, MS Forms, and Whiteboards.
• Tool Limitations: Migration tools such as Quest ODM and ShareGate had constraints requiring custom strategies.
• User Identity Mapping: Required precise mapping of Riscure users to Keysight accounts, including handling external users and chat duplication.

Proposed Solution

Netwoven’s solution was structured into six milestones, each with detailed deliverables and strategic planning:

Milestone 1: Project Initiation

• Environment onboarding and access setup
• Kick-off meetings and collaborative infrastructure (MS Teams)
• Delivery of Infrastructure & Access Requirements document and Kick-Off deck

Milestone 2: Assessment & Analysis

• Tenant health checks and configuration comparisons
• Inventory reports for all in-scope workloads
• Migration strategy workshops and decision matrices

Milestone 3: Migration Design & Preparation

• Validation of test migration infrastructure and bandwidth
• Finalization of migration mappings and strategy documentation

Milestone 4: Pilot Migration

• Migration of 10 pilot users
• AD security group setup and communication planning
• User Acceptance Testing (UAT) and feedback collection

Milestone 5: Production Migration

• Migration of:
  • 200 mailboxes (<3TB)
  • 33 SharePoint sites (<4.1TB)
  • 200 OneDrives (<1.2TB)
  • 25 Teams (including chats and channels)
  • 10 Viva Engage communities
  • 30 Power Automate flows, <10 PowerApps, MS Forms (manual)
• HTML archiving for older Teams messages
• ShareGate used for Teams channel conversations

Milestone 6: Post-Go-Live Support

• Two weeks of support for issue resolution and user assistance
• Final retrospective and lessons learned

Benefits

Strategic Consolidation

The migration enabled Keysight to consolidate its digital assets under a single Microsoft 365 tenant, reducing fragmentation and improving operational efficiency across departments.

Enhanced Governance & Compliance

By centralizing user identities and collaboration tools, Keysight strengthened its data governance, access control, and compliance posture—especially critical for a global enterprise handling sensitive data.

Improved Collaboration & Productivity

Unified access to Teams, SharePoint, and OneDrive improved cross-functional collaboration, reduced silos, and enabled seamless communication between previously separate entities.
