Tenant Migration
When M&A, site reorganization or stronger governance calls for it, weconsolidating Microsoft 365 tenantsprovide end-to-end support—from planning through migration to stabilization. We merge tenants scattered across multiple and overseas sites into one and handle identity management and security design with Entra ID.
Do any of these sound familiar?
PAIN POINTS
- M&A or reorganization has left M365 split across multiple tenants
- Identity and permissions differ by site, so security can’t be controlled
- No in-house know-how to migrate email, Teams and SharePoint
- You want to centralize overseas IT management at HQ due to geopolitical risk
APPROACH
Our solution
We proceed in stages—from assessment to migration planning, validation, the main migration and stabilization. We centralize identity and access with Entra ID and design unified security policy via conditional access. Our strength is coordinating with local sites in JP/EN/ID even when overseas tenants are involved.

Frequently asked questions
Can you migrate without stopping our operations?
We default to a staged migration with a pilot to keep business impact minimal, and we align the cutover timing with your business calendar.
Can you handle consolidations involving overseas sites?
Yes. We have consolidated overseas tenants into a Japan HQ and can coordinate with local staff in JP/EN/ID.
Can you also handle post-migration operations?
Combined with our Microsoft 365 Help Desk (24/365), we can support post-migration inquiries and operations end to end.
Can we keep our custom-domain email after consolidation?
We define domain handling when designing the migration approach and present a plan tailored to your requirements during the assessment.
Can you support environments tied to on-premises Active Directory?
We assess your current configuration—including Entra ID design—and propose an approach. Since the path depends on your setup, start by sharing your current state.
How long does migration take?
It depends on the number of users, data volume and sites. After the assessment we present a concrete schedule including the staged migration.
Can we also clean up unused licenses during consolidation?
Yes—we can also help inventory and optimize licenses as part of the consolidation.
