How IT Teams Can Ace Office 365 Tenant-to-Tenant Migration

A tenant-to-tenant migration for business can seem challenging, but with a solid roadmap in place, IT teams can make it happen. Tenant-to-tenant migration is the process of moving users, data, and resources from one Microsoft 365 tenant to another.

Whether it’s a business merger, acquisition or just a restructuring of cloud tenants, many companies have the need to perform Tenant migrations at some point in time. With proper planning and the right tools, any Microsoft 365 tenant-to-tenant migration can be seamless and business-as-usual.

Understanding Office 365 Tenant-to-Tenant Migration

At its simplest, a tenant migration is moving data and user accounts from one Microsoft 365 tenant (e.g., Office 365) to another. In most cases, Office 365 tenant migration is for companies going through structural changes such as mergers, acquisitions, divestitures, or just optimizing their IT infrastructure. Whether you’re migrating within the same company or between different Microsoft 365 tenants, the goal is to ensure your data and users get migrated securely and smoothly.

It may seem daunting, but it can be broken down into simple steps. Here are the key things to consider before you start the migration:

What to Move: Make a list of all the resources that need to be moved, including email data, files, SharePoint sites, Teams, OneDrive, etc. Knowing what needs to be moved will help simplify the process.

Source and Target Tenants: Before you start the migration, do a thorough analysis of both the source and target cloud tenants. This will prevent surprises and ensure the target tenant is ready to receive the data.

Common Use Cases for Tenant-to-Tenant Migration

There are many scenarios that require a tenant-to-tenant migration:

• Business Mergers: Two companies become one and need to consolidate their Microsoft 365 tenants.
• Business Acquisitions: One company buys another and needs to migrate the acquired company’s data to the parent company’s tenant.
• Reorganizations: Moving employees or business units to different cloud tenants for compliance, geographic or operational reasons. Knowing your reason will help you decide the best approach.

Tenant-to-Tenant Migration Approach

When you plan your migration, one of the first decisions is whether you’ll be moving into one tenant or multiple tenants. Let’s break it down:

Single Tenant Migration

This is the most common. All your users, data, and resources are moved into one tenant. It makes collaboration easier, and all users are working in the same environment. It is a more straightforward job to secure and manage one tenant.

Multiple Tenant Migration

For companies with multiple business units, global teams, or different geographic locations, moving to multiple cloud tenants may be required. However, this complicates collaboration as users across different tenants need to use guest access, which adds to security management.

Tenant-to-Tenant Migration Best Practices

Follow these best practices:

1. Create a Solid Migration Plan: A plan will help you navigate the migration and avoid the common pitfalls. Make sure to consider data loss, downtime, and big data moves.
2. Fix Permissions and Access First: Fix any permissions or access issues in the source tenant before you migrate to avoid bringing over security holes.
3. Clean Up Your Source Environment: A migration is a great opportunity to clean up and reorganize. Clean out old or unused data and restructure your content so users will adopt the new system.
4. Have a Backup Plan: Backing up data before you start the migration means if something goes wrong, you can restore the data to avoid losing it forever.

Concurrent Migrations for Complex Scenarios

If you have multiple cloud tenants or large migrations, concurrent migrations might be the way to go. This runs multiple migration tasks at the same time, reducing the overall time of the migration. It’s good for organizations with petabytes of data or multiple departments or business units.

Best practices for concurrent migrations:

• Automate Where You Can: Use tools that can automate to simplify the process and reduce human error.
• Monitor: Keep an eye on the migration to catch issues early.
• Stagger Migrations: Don’t overload your network by migrating in a way that will put strain on your infrastructure.

Cross-Tenant Migrations: The Way to Go

For organizations with multiple Microsoft 365 environments or going through mergers and acquisitions, cross-tenant migrations are required. This type of migration means moving data between different Microsoft 365 tenants. Whether migrating from an Office 365 tenant to a Microsoft 365 tenant or between two Microsoft 365 tenants, cross-tenant migration means business continuity.
