Microsoft Teams Tenant to Tenant Migration: A Complete Guide
After COVID, Microsoft Teams became popular among users because during COVID, I have seen many organizations rely on Teams for chats and project coordination. But in the situation where a company merges, the most common challenge they face is Microsoft Teams tenant to tenant migration.
Personally, I have seen many users getting confused while performing this process because they don’t understand the process and have the right planning to begin with. Many IT professionals struggle to migrate Microsoft Teams from one tenant to another because Microsoft doesn’t offer a built-in feature. In this article, I will walk you through everything that is important, best practices and a reliable solution to migrate teams from one tenant to another securely.
What is Microsoft Teams Tenant to Tenant Migration?
In simple words, it is the process of transferring all Teams data from one Microsoft 365 tenant to another. A tenant is nothing but your organization’s dedicated Microsoft 365 environment. Users need to perform this process when:
- The company is going through a merger ot acquisitions
- When the organisations selling itself
- Reorganising the company hierarchy
- Merger required between accounts or tenants into one
Each tenant includes:
- Teams and channels
- Private or group conversations
- SharePoint site data
- OneDrive files
- User permissions
If the merger is not handled properly, the risk of losing the data is always there. This is the reason organisations always have a proactive approach to migrate Microsoft Teams from on tenant to another without affecting the workflow.
Most of the organisations assume it is an easy process, yes, this is true but with the right approach. If not then they face complexity to migrate Teams from one tenant to another.

Why Migrate Microsoft Teams From One Tenant to Another
The day I started working on the Microsoft Teams tenant to tenant migration, I realized that understanding the core features is very important before starting the process. These features help users in making sure a smooth and hassle- free migration without risking the loss of data. Here are the features that I recommend understanding first:
- Complete data coverage: A proper migration should include everything such as Teams, channels, chats, files, and permissions so that nothing gets missed behind during the process.
- Chat and conversation migration: It becomes an important task to move both private chat and channel conversations without interrupting the structure.
- Permission and user mapping: Mapping users in a correct way is important between the old and new tenants to keep access rights as they are and avoid confusion.
- SharePoint and OneDrive integration: Since Teams is dependent on both SharePoint and OneDrive, a careful and secure migration make sure that all files are accessible after the move.
- Preservation of structure: The layout of Teams, channels, and tabs should remain the same so users get the data at the same time when they need it.
- Incremental migration support: Moving data one by one in the form of stages instead of doing it in one go reduces risks and minimizes downtime that occurs.
- Pre-migration analysis: A proactive approach is always good, so reviewing everything before starting the whole process helps identifying the potential issues early and make sure a smoother migration.
Why is Teams Migration So Complex?
The most common question that I heard from many users is “Can’t we just copy everything?” Unfortunately it is not that simple a process to perform. Microsoft Teams tenant to tenant migration involves multiple interconnected services like Exchange Online, SharePoint Online, and OneDrive. Here are some challenges that I faced:
- Chat migration: Private chats and channel messages are stored in hidden mailboxes. In order to migrate it needs specialized methods to migrate Microsoft Teams from one tenant to another without interrupting message history.
- Permission mapping: User accounts need to be in the destination tenant. During the process to migrate Teams from one tenant to another, you need to align the source users to destined users correctly.
- SharePoint and OneDrive dependencies: Every Team has its own SharePoint site. If the migration can’t be done properly files become inaccessible.
- Downtime risk: A proactive approach is very important. If you don’t do the homework properly then it can trigger problems and interruptions in communication.
Pre-Migration Planning
Pre-planning plays a vital role before starting any Microsoft Teams tenant to tenant migration. Here is the pre-planning that I personally follow:
Step 1: Assessment
I first check:
- Number of Teams you have
- How much data do you need
- Total number of users
- Apps and integration
These points help me in understanding how to migrate Microsoft Teams from one tenant to another.
Step 2: Prepare destination tenant: Create a new user account in the new tenant. In order to avoid confusion later you need to carefully map each user correctly.
Step 3: Back up data: It is always important to take a backup of email data before starting the process.
Step 4: Pilot migration: It is always important to prefer migrating a few Teams first to test performance, instead of migrating everything in one go.

Process for Microsoft Teams Tenant to Tenant Migration
Based on my experience, I have seen many users go straight to the migration without understanding the proper steps, which eventually causes errors in the future or during the process. Having proper planning makes the Microsoft Teams tenant to tenant migration much easier. Here are the steps that I follow:
- Connect source and destination tenants: First, you need to link the source and destination tenants so that data gets migrated to them smoothly.
- Prepare user accounts: Make sure that all the users already exist in the destination tenant and are properly matched with their original accounts to avoid permissions and problems in the future.
- Select data for migration: Select the specific data that you want to move, including Teams, channels, chats, and files instead of transferring all the data which includes unnecessary ones as well.
- Configure settings and permissions: before initiating the process always set up roles, policies, and access levels in the destination tenant.
- Start the migration process: Start the process in small batches first to reduce system load and avoid any kind of hassle.
- Monitor the migration: Keep an eye on the migration process so that you can quickly identify the issue and resolve it.
- Validate migrated data: Once the process is finished check whether all Teams, files and permissions have been transferred correctly or not.
Manual vs Automated Migration
Most of the time when organizations try to Microsoft Teams tenant to tenant migration manually. They face some challenges.
Manual Approach
Microsoft offers limited capabilities through PowerShell scripts. However:
- There are always limitations in the migration of chats
- Users need to have technical expertise because advanced scripting knowledge is required.
- It is a time-consuming process
- Human errors are always there
It becomes a difficult task to fully migrate Microsoft Teams from one tenant to another using the native tools.
Automated Approach
Using a professional tool makes a big difference by making the process to migrate Teams from one tenant to another much easier while preserving the structure and permissions.

Can PowerShell Handle Migration?
PowerShell can help with some administrative tasks, but it is unable to perform a complete migration on its own. Using PowerShell you can:
- Create Teams and channels in the new tenant
- Export the user list from the old account into the new one
- Set up the Teams structure again
- Able to add owners and members to each Teams
- Set up the policies that are required
However, PowerShell is unable to migrate directly:
- Personal chat history
- Planner data
- Apps and tab settings that are preserved
- Complete the SharePoint site structure automatically
The scripts are good for assisting the process, but they are unable to migrate Microsofts Teasm from one tenant to another using only PowerShell.
Security & Compliance Considerations
During Microsoft Teams tenant to tenant migration, security is something that is non-negotiable. Since organizations carry sensitive business data, maintaining security and compliance is important during the process. Here are some key points that I personally follow:
- Data encryption: Make sure that the data is encrypted during the migration to avoid unauthorised access.
- Access control: Only the right people like the authorised users and admins should havve the access to the tools and data.
- Compliance requirements: Make sure that your organisation is following the GDPR and internal policies during the process of moving data between tenants.
- Audit logs: Keep a record of all migration activities so you know exactly the issue and can fix it ASAP
- Data integrity: Make sure that files, chats, and metadata remain same during the migration.
Secure authentication: Use strong and unique login methods to protect the data from unauthorised access.

But the reality is that the important part comes after that, checking everything carefully.

Based on my experience, I have seen many companies make the same mistakes in Microsoft tenant to tenant migration:
- Avoiding the chat history migration
- Ignoring whether user accounts are mapped correctly
- Skipping pilot migration before the final process
- Forgetting to check the SharePoint connection and dependencies
- Without preparation going straight to the migration process
