The admin access challenges of tenant consolidation

Living in one big tenant isn’t always easy: Multi-tenant Microsoft 365 is complex—but it naturally enforces privilege segregation. Consolidating into a single tenant breaks this, putting all IT admins in one shared environment with access to each other’s mailboxes, configurations, devices, and more.

‍The time burden of tenant-to-tenant migration: Beyond the access issues, consolidation takes serious effort. It requires deep visibility into users and mailboxes and a major onboarding lift that can tie up IT resources and delay key initiatives. Without automation or strong reporting, organizations turn to PowerShell and costly consultants—driving up costs and reducing the value of consolidation.

Simplify Microsoft 365 tenant migration and consolidation with CoreView

Make tenant consolidation and migration simple, secure, and successful.

Plan your migration

CoreView gives you enhanced visibility into everything in the tenants you're consolidating—users, Teams groups, apps, and other resources. Easily identify inactive items that don’t need to be migrated, saving time and effort.

Maintain tenant segmentation

CoreView’s unique Virtual Tenant segmentation capabilities make it possible for different IT teams to share the same tenant. Each team operates in its own segment, with privileged access limited to only their own users and resources.

Automate the user onboarding process

CoreView’s task automation makes it easy to onboard users at scale. Build onboarding workflows using 150+ out-of-the-box automation actions, and integrate custom steps using PowerShell or third-party API calls.

Enforce least privilege post-migration

The principle of least privilege is key to strong security. CoreView enforces virtual tenant segmentation, ensuring IT admins from different environments operate only within their own boundaries—even after migration. Admins can’t manage users, licenses, or resources outside their assigned scope.

Segment with 400+ attributes

Apply granular controls using over 400 attributes—like user, device, Teams phone number, and mailbox. With CoreView, you can:

Create Virtual Tenants that scope a user's access
Delegate precise permissions within each segment
Consolidate without introducing privilege creep

De-risk the consolidation process

Microsoft 365 tenant consolidation is a major undertaking. CoreView helps you de-risk the process by maintaining operational efficiency, mitigating security risks, reducing administrative complexity, and controlling project costs.

Automate cross-tenant migrations

User onboarding during consolidation can be overwhelming. CoreView automates the process, allowing you to onboard hundreds or thousands of users into the target tenant—without overloading your IT team.
