Microsoft Teams Tenant to Tenant Migration
Microsoft Teams tenant-to-tenant migration moves supported Teams data from a source Microsoft 365 tenant to the required Team sites in a target tenant. The EdbMails Teams workflow is built around source and target tenant preparation, Team-site selection, source-to-target mapping, migration progress monitoring, incremental migration and post-migration log review.
EdbMails lets administrators connect the source and target Microsoft 365 environments, load the available Team sites, select the Teams in scope, map source Team sites to the required destination sites, run the migration, and review migration logs. For projects involving channels or private and group chats, use the separate workload-specific Teams Channel and Teams Chat migration workflows rather than assuming every Teams component is handled by the broad site migration path.
When do organizations need Teams tenant-to-tenant migration?
Microsoft 365 tenant consolidation or restructuring.
Merger or acquisition where Teams need to move into a receiving tenant.
Domain, provider or organizational changes that require a new Microsoft 365 destination.
Movement of selected Team sites into another tenant while keeping the broader source environment active.
Prepare the source and target Microsoft 365 tenants
Before migration, keep the SharePoint server URL, SharePoint Admin Center URL and Microsoft 365 Global Administrator account information ready for both tenants. The EdbMails Teams workflow also requires manual Microsoft Entra ID application registration for the source and target tenant connections.
Confirm that the required target Team sites exist or are ready to be created according to the documented EdbMails workflow, and make sure the administrator has the required access to the source and target Team sites involved in the project.
Load and select the Team sites in scope
EdbMails can load the available Team sites from the source environment.
Administrators can select the required Team sites and proceed with only the migration scope needed for the target environment.
Additional sites can be loaded using CSV where required by the documented workflow.
Map source Team sites to the target tenant
EdbMails supports automatic mapping, manual mapping and previous migration mapping. Review the mapping before starting the migration, particularly where Team names or destination structures differ between source and target.
Migrate in manageable batches
EdbMails supports simultaneous migration of multiple Team sites. For larger tenant moves, organize the migration into manageable batches so mapping, progress, logs and target validation can be reviewed before the next wave.
Use incremental migration for later source changes
If users continue working in the source environment during a staged project, perform a later incremental migration for supported new or modified data. EdbMails uses locally stored encrypted migration metadata for the incremental check, and the same migration computer should be used for subsequent runs of a previously migrated Team site.
Monitor migration and validate the target
EdbMails provides migration progress, pause and resume controls, and a View Log option. After each migration wave, review completed, skipped or failed items and verify representative Team sites and user access in the target tenant before closing the batch.
Frequently Asked Questions
What is Microsoft Teams tenant-to-tenant migration?
It is moving supported Teams data from a source Microsoft 365 tenant to the required Team sites in a target tenant.
Are channels and chats handled by the broad site migration?
No. Use the separate Teams Channel and Teams Chat migration workflows for channel messages and private or group chats, rather than assuming every Teams component is handled by the broad site migration path.
How do I prepare the source and target tenants?
Keep the SharePoint server URL, SharePoint Admin Center URL and Microsoft 365 Global Administrator account for both tenants, complete manual Microsoft Entra app registration, confirm the target Team sites, and ensure the administrator has access to the Team sites involved.
Can EdbMails create the target Team sites?
Confirm that the required target Team sites exist or are ready to be created according to the documented EdbMails workflow.
How do I map source Team sites to the target?
EdbMails supports automatic mapping, manual mapping and previous migration mapping. Review the mapping before starting, particularly where Team names or destination structures differ.
Can multiple Team sites migrate at once?
Yes. The guide documents simultaneous migration of multiple Team sites, which helps with larger tenant moves.
Should I migrate the whole tenant in one job?
No. Organize the migration into manageable batches so mapping, progress, logs and target validation can be reviewed before the next wave.
Can users stay active during the migration?
Yes. Run a later incremental migration for supported new or modified data, using the same migration computer for subsequent runs of a previously migrated Team site.
Does EdbMails support pause and resume?
Yes. EdbMails provides migration progress, pause and resume controls, and a View Log option.
How do I validate the target tenant?
After each wave, review completed, skipped or failed items and verify representative Team sites and user access in the target tenant before closing the batch.
Is tenant-to-tenant migration the same as cross-tenant migration?
They are closely related. Cross-tenant migration emphasizes organizational boundaries and identity changes across separate Microsoft 365 tenants.
