Mastering the Art of Migration: Transitioning Microsoft Teams from One Tenant to Another


Companies today depend heavily on digital workplace tools like Microsoft Teams for collaboration purposes. This article details the intricate process of moving Teams tenants between tenants. Let’s navigate this maze together and discover efficient methods of seamless transfer – while keeping to our article title’s definition of “teams tenants to tenants”.

Understanding the Migration Terrain

Microsoft Teams has quickly become an essential element of modern workplace collaboration and communication, but companies that wish to alter their digital infrastructure due to mergers, acquisitions or consolidation plans face unique difficulties when transitioning between tenants. Transitions involving Microsoft Teams may prove especially tricky.

Undertaking a successful transition does not have to be challenging. By adopting a methodical and strategic approach and employing appropriate tools, companies can ensure their transition is as seamless as possible. But before diving too deep into this process, we must first become acquainted with potential scenarios for migration:

Inter-Tenant Migration

Inter-Tenant Migration can occur when teams move from one Microsoft 365 tenant to another – typically as part of mergers and acquisitions.

Intra-Tenant Migration: When restructuring takes place in one tenant, intra-tenant migration usually occurs comparatively easily as moving Teams between workspaces within that tenant can help ensure continuity for business continuity.

This article will focus on the latter aspect and offer you an in-depth guide for moving Microsoft Teams between tenants.

Pre-Migration Phase

Prepare for Takeoff

Switching to Microsoft Teams can be like moving an established community into a different city – it requires careful preparation, communication, and coordination in order to be successful. Before embarking on this migration journey, take note of these key points before getting underway:

Comprehensive Inventory Analysis

Before moving, it is vitally important that you are fully informed about what needs to be relocated. Examine Microsoft Teams’ architecture and identify all channels associated with teams, channels and information. Tools like SharePoint Migration Manager can make this process simpler.

Develop a Strategic Migration Plan

Planned migrations are essential in order to minimize risks and ensure everything runs smoothly during the transition process. Your plan should outline which types of data will be transferred, how it will be transported, any transfer restrictions that must be adhered to and any possible risks and mitigation strategies which should be employed during this endeavor.

Clean-Up and Organize

Clean-up is an essential step when planning for migration. Sort through or eliminate old channels and teams to reduce unnecessary clutter in your new space, and instruct users on maintaining their personal areas.

Communication and Training

Be sure to keep everyone updated. Be sure to clearly communicate any upcoming changes or possible downtime to all users affected, as well as providing necessary instructions to assist users with adapting to a brand new tenants environment.

The Migration Phase: A Strategic Lift and Shift

Once pre-migration tasks have been completed, it’s time to launch this process. Let’s examine all of the steps necessary for ensuring a successful “teams Tenant to Tenant Migration”.

Migrate Users and Permissions

At the core of migration is user and permission movement. Azure Active Directory provides a useful solution to move clients from an origin tenant tenant to their final destination tenant tenant.

Migrate Teams and Channels

After users migrate, channels and teams need to be transferred. Unfortunately, Microsoft does not offer an integrated solution for this, meaning third-party tools like AvePoint, BitTitan or ShareGate may need to be utilized.

Migrate Teams Data

Data migration is the next step. Teams data includes tabs, conversations and files stored within SharePoint that need transferring – for this purpose Microsoft offers its SharePoint Transfer Tool; other forms of data could require third-party tools.


After any migration, it is essential to make sure everything runs as intended. Examine user access rights, data integrity and functional teams functionality before declaring success or failing.

Post-Migration Phase: Landing and Settling Down

Once data have been transferred, migration doesn’t end – its post-migration phase is just as critical to ensure a seamless transition.

User Validation and Troubleshooting

Once testing has concluded, it’s now up to users to evaluate and validate the changes made during this phase. Collect feedback, identify any problems encountered and find solutions before moving forward with implementation.


Once all checks have been performed and validated, it is time to decommission the tenant that served as source. It’s important to do this properly so as not to lose data in this process.

Continual Training and Support

Continue to provide support and training to users to aid them in adapting to the new environment.


Transitioning tenants between spaces can be a complex and time-consuming task, but with careful planning and implementation you can minimize disruptions for a smoother experience. Utilizing the appropriate tools and collaborators are crucial in this regard.

Successful migration requires consistency across each stage – pre-migration, migration and postmigration. By following this detailed guideline, companies can guarantee an easier transition and turn tenant to tenant migration into a success story for their teams.
