How to Migrate Microsoft Teams Groups/Channels with Complete Historical Chat and Conversation History Between Tenants?

We need to migrate Microsoft Teams data from one Microsoft 365 tenant to another using native Microsoft-supported tools/methods.

The requirement includes:

  • Teams/groups and channels
  • Complete historical chat and conversation history
  • Historical messages and replies
  • Team/group members and ownership
  • Files and attachments shared in conversations/channels
  • Existing conversation structure
  • Original dates/timestamps and participants, where supported

The migration involves multiple existing Teams/groups, and retaining historical chat/conversation data is a critical requirement.

Could anyone please advise on the native Microsoft-supported approach for this scenario? Specifically:

  1. Can Microsoft 365 Migration Orchestrator migrate complete Teams chat/channel history across tenants?
  2. Can Teams, channels, memberships, messages, replies, and files be migrated natively?
  3. If not, what combination of Migration Orchestrator, SharePoint cross-tenant migration, Microsoft Graph APIs, or other Microsoft-native tools should be used?
  4. What are the documented limitations for historical messages, timestamps, participants, attachments, and conversation structure?
  5. Is there a recommended Microsoft-supported pilot/validation approach before performing the full migration?

We are looking for a native Microsoft approach without relying on third-party migration tools, if technically possible.

    Hi @Gowtham K

    Currently, I have not found a Microsoft-native solution that can perform a complete tenant-to-tenant Teams migration while preserving the full team structure, channels, channel conversations, replies, memberships, files, and historical context.

    From what I understand, Migration Orchestrator supports workloads such as Exchange mailboxes, OneDrive, Teams chats, and Teams meetings. It is designed for user-centric workload migrations and is not documented as a solution for migrating shared collaboration data such as Teams structures, channels, or SharePoint team/channel sites.

    You can refer via: Migration Orchestrator overview

    Additionally, other Microsoft-native options each address only specific parts of the migration, for example:

    SharePoint cross-tenant migration: Focuses on migrating SharePoint content, including files associated with Teams. It is a separate workload with its own requirements and does not recreate Teams conversations or automatically relink files to historical messages.

    Microsoft Graph migration APIs: Can be used to create Teams and channels, and import historical messages into Teams. This approach supports preserving message attribution and historical timestamps during migration scenarios. However, it requires custom development and thorough validation, and is not intended as a complete end-to-end tenant-to-tenant Teams migration solution. As a result, some Teams experiences and content types may not be preserved with full fidelity after migration.

    Please note that this summary is based on my own research and understanding of the currently available Microsoft documentation, so it may not fully address all aspects of your specific migration scenario. Since migration capabilities and limitations can vary depending on the workloads involved, your tenant configuration, and business requirements, I would recommend engaging Microsoft Support for more detailed guidance and validation of your migration plan.
