M365 Tenant Consolidation

Mergers and acquisitions often leave organizations with multiple Microsoft 365 tenants—creating silos, inefficiencies, and increased security risks. Without consolidation, IT teams face mounting complexity and users experience fragmented access, collaboration issues, and inconsistent policies.

One Tenant. Total Control.

R3 helps you consolidate your M365 environment into a single, unified tenant—streamlining management, improving collaboration, and hardening your security posture. Whether you’re managing multiple tenants post-acquisition or preparing for future growth, we deliver a smooth, secure transition that sets your organization up for long-term success.
