Foremost Magnets and Foremost Print – Microsoft 365 Tenant Merge

Foremost Magnets and Foremost Print are specialist businesses operating within the manufacturing and print sector, providing trade-focused promotional products and complex print production services. Foremost Magnets supplies custom flexible fridge magnets for marketing and promotional campaigns, while Foremost Print delivers specialised printing, sourcing, and distribution services for high-quality materials. Together, they support clients across a range of industries with precision, quality, and reliable delivery.

Challenges

Following the alignment of the two businesses, there were multiple Microsoft 365 environments in use.

This created a fragmented IT setup, with:

  • Separate email systems and user identities
  • Disconnected file storage across SharePoint and OneDrive
  • Inconsistent permissions and access controls
  • Limited collaboration between the two businesses
  • Increased complexity in managing systems and security

The objective was to consolidate both environments into a single, streamlined platform without disrupting daily operations.

Solution

We designed and delivered a structured Microsoft 365 tenant-to-tenant migration into a unified environment.

The focus was on simplifying IT management while improving collaboration and security.

This included:

  • Consolidating all users, mailboxes, and domains
  • Migrating SharePoint, OneDrive, and Teams data
  • Standardising permissions and access controls
  • Creating a consistent structure across the organisation
  • Ensuring secure access and data integrity throughout

The result was a single Microsoft 365 tenant supporting both businesses.

Implementation / Process

We followed a phased and controlled migration approach to ensure minimal disruption.

  1. Discovery & mapping – identified users, mailboxes, data, and dependencies across both tenants.
  2. Design & planning – created a unified structure aligned to how the combined business operates.
  3. Phased migration – moved email, files, and services in controlled stages.
  4. Permissions alignment – ensured correct access levels across the new environment.
  5. Validation testing – confirmed data integrity, access, and system functionality.
  6. Cutover & cleanup – completed migration and removed legacy tenant access.

This ensured continuity of service while transitioning to the new environment.

Results/Benefits

The business now operates from a single, consistent Microsoft 365 platform.

  • Unified communication and collaboration tools
  • Improved access to shared data and systems
  • Simplified IT management and administration
  • Consistent security policies and access control
  • Reduced risk from duplicate data and legacy environments
