Can Microsoft Teams be migrated from one tenant to another without losing data?

Yes, Microsoft Teams can be migrated from one Microsoft 365 tenant to another, but the amount of data that can be transferred depends on Microsoft API limitations and the migration method used. The SysInfo Microsoft 365 Tenant to Tenant Migration Tool provides a dedicated option for migrating Teams data between tenants. It supports public and private channels, channel messages, files, tabs, apps, Planner content, conversations, replies, reactions, meeting links, and other supported components. The tool also provides one-to-one user mapping, incremental migration, and live migration reports, helping administrators maintain the correct structure and avoid unnecessary duplicate transfers. However, certain Teams components, including announcement headers, recorded meetings, and shared channels, are not supported because of Microsoft Teams service and API restrictions. Therefore, organizations should review supported data, perform a pilot migration, and verify the results before starting a complete tenant-to-tenant Teams migration.
