From 5 Tenants to 1: M365 Tenant Migration of a Tech Company

After a massive merger, a tech company faced the complex task of managing five separate Microsoft 365 tenants, each with their own email, SharePoint, OneDrive, and Teams services. Although these services were great on their own, they created a complex scenario of management, collaboration, and security and compliance visibility.

To solve this problem and ensure that management and collaboration are seamless, the tech company partnered with CloudFuze to execute a Microsoft 365 tenant to tenant migration to combine all five tenants into one unified Microsoft 365 environment without affecting their daily business operations.

This guide elaborates on how we at CloudFuze helped a tech firm in consolidating multiple Microsoft 365 tenants into a single, fully integrated environment.

Key Takeaways:

  • Merging multiple Microsoft 365 tenants makes IT management and administration much simpler.
  • CloudFuze preserves metadata, timestamps, and permissions when transferring large volumes of data.
  • Enterprises can easily manage compliance and regulatory requirements using comprehensive audit trails.
  • Merging tenants gives a scalable Microsoft 365 environment for future mergers and acquisitions or business expansion.

The Challenge: Overcoming Microsoft 365 Complexity at Scale

The tech company faced the following challenges:

  • Migrating over 12,000 mailboxes
  • Transferring over 50 TB of SharePoint and OneDrive data
  • Migrating over 3,500 Microsoft Teams channels, including conversations, files, and tabs
  • Preserving metadata, timestamps, and folder structures for all workloads
  • Compliance and audit trail requirements

Migrating thousands of users and terabytes of data across various tenants is a complex process. Manual migration processes or IMAP-based migration processes can result in data loss, incorrect metadata, and extended downtime.

The technology company needed a reliable, secure, and scalable solution for migrating:

  • Mailbox data with preserved metadata and timestamps
  • SharePoint & OneDrive data with preserved permissions and sharing links
  • Microsoft Teams data with preserved channels, chats, and files
  • Compliance and audit requirements for sensitive data
