Navigate common tenant-to-tenant migration challenges

Migrating Office 365 tenants isn't just a data transfer job. It’s a complex operation with plenty of hidden risks.

No transparency on service usage

Each Microsoft 365 service holds critical data, permissions, and automations. Without full visibility, migrations stall or miss important connections.

Outdated or duplicated content

Legacy SharePoint sites, orphaned Teams, and duplicate files cause confusion, increase risk, and drive up storage and maintenance costs.

Misaligned access and permissions

Manually copying over permissions without understanding relationships between users, groups, and data can lead to compliance gaps

Overprovisioned licenses

Unused or misallocated licenses drive up costs, create unnecessary overhead, and make license planning a post-migration nightmare.

Disrupted automations & workflows

Power Platform workflows and scripts can silently break if dependencies aren’t identified and addressed before migration.

"As with all organizations, we at Specialist Risk Group want to use every option available to ensure secure data in Microsoft 365 and minimize the risk of unauthorized access where possible. Most, if not all information is available in the Microsoft 365 admin centers of the respective services, but there is no way to view it in one place in a simple contextual way. This is one area where Rencore's governance software excelled."

Frequently Asked Questions

What is a tenant-to-tenant migration in Microsoft 365?

A tenant-to-tenant migration typically occurs during company mergers, acquisitions, or restructurings. It involves moving all or parts of users, data, and services from one Microsoft 365 tenant to another. If you're just starting out, here are five essential tips to keep in mind when migrating to Office 365.

How to efficiently migrate users between Office 365 tenants?

Instead of recreating users manually, it's more efficient to prepare a permission and group strategy in advance. Once set up, you can assign new users to these pre-defined settings to maintain consistency. It's especially important to follow best practices for M365 tenant segmentation and security to avoid compliance gaps during restructuring.

What services does Rencore support during M365 tenant-to-tenant migration?

Rencore acts as a pre-migration assessment platform, providing full visibility into Microsoft 365 services. So you can prepare your environment thoroughly and avoid surprises.

How does Rencore help reduce migration risks?

Rencore maps relationships between users, data, and processes. It enables license and permission model design before migrating users, ensuring smoother transitions and compliance. If your migration is part of a divestiture or spin-off, this webinar on assessing M365 tenants for a business carve-out offers deeper insights.

How does Rencore support SharePoint migration?

Rencore doesn’t move content directly, but it plays a key role in preparing your SharePoint environment for migration. It helps you identify outdated or duplicate sites, map permissions and access, and gain full visibility across usage and ownership. Whether you're planning to migrate a SharePoint site to another tenant, consolidate sites, or ensure proper SharePoint governance post-migration, Rencore gives you the insights to do it securely and efficiently.
