When businesses merge, acquire new sites or restructure, they often end up with multiple Microsoft 365 tenants. That means separate identities, mailboxes, Teams, SharePoint libraries and admin portals – all harder to manage and more expensive to run.
IT365 delivers clean, well-planned multi-tenant migrations that bring everything under one secure, unified Microsoft 365 environment. We handle the technical complexity, protect your data, and ensure users experience a smooth transition.
Why Businesses Need Tenant-to-Tenant Migration
Multiple tenants create inefficiency, inconsistency and unnecessary admin. A migration project helps you:
- Consolidate users, mail, Teams, SharePoint and OneDrive
- Improve security with one central identity and policy set
- Reduce licensing waste and duplicate subscriptions
- Standardise compliance, MFA, conditional access and device control
- Simplify support, permissions and long-term management
Whether you’ve merged with another company, expanded into new sites, or simply need to clean up legacy tenants, we make the process smooth and safe.
What We Deliver
Identity & User Consolidation
We migrate users cleanly into the target tenant, aligning identities, MFA, security groups and roles. This ensures access is correct, secure and consistent from day one.
Mailbox & Email Migration
We manage full mailbox moves, send/receive coexistence and cutover planning. Users keep their data, folders, calendar items and access without losing productivity.
SharePoint & OneDrive Migration
Documents, libraries, permissions and sharing links are moved across with minimal disruption. We ensure structure, ownership and security are preserved during the transition.
Microsoft Teams Migration
We migrate teams, channels, chat history (Where supported), membership and permissions. We communicate clearly with users so they know what to expect before and after migration.
Security, Compliance & Policies
When everything moves under one tenant, we align your MFA, conditional access, device compliance, retention policies and governance – so your entire organisation operates under one secure standard.
Licensing Review & Clean-Up
Migrations often reveal duplicate, unused or misaligned licences. We help you clean this up and ensure you only pay for what you need.
