What is Microsoft Teams Migration?

Microsoft Teams migration is the process of transferring Teams, channels, conversations, files, and collaboration data from one Microsoft 365 tenant to another. Organizations typically perform Teams migrations during:

  • Mergers and Acquisitions (M&A) - Consolidating acquired company Teams into the parent tenant
  • Divestitures - Separating business units into independent tenants
  • Tenant Consolidation - Merging multiple tenants into a single environment
  • Rebranding - Moving to a new tenant with updated company identity

Key Migration Capabilities

  • Channels - Both standard and private channels with full message history
  • Files and documents - SharePoint-backed files with versions and metadata

Everything you need to know about Teams migration

What Teams data is migrated?

Cloudiway migrates Teams structure, channels (standard and private), channel messages, files, tabs, connectors, memberships, Planner tasks, wiki content, and team settings. The complete Teams environment is transferred with full fidelity.

Are private channels supported?

Can I migrate Teams between Microsoft 365 tenants?

Yes, Cloudiway fully supports cross-tenant Teams migration, which is essential for mergers, acquisitions, divestitures, and tenant consolidation projects.

What about private 1:1 chats?

Private 1:1 chats are stored differently in Microsoft Graph and require separate migration using our chat migration capability. Contact our team for guidance on comprehensive chat migration.

Is there downtime during migration?

Cloudiway's delta sync technology minimizes downtime. Users can continue working during pre-staging, with only a brief cutover window needed for final synchronization.

How long does a Teams migration take?

Duration depends on the number of Teams, channels, and data volume. With delta sync, you can pre-stage data over days or weeks, then complete the cutover quickly with minimal disruption.

Are Planner boards migrated?

Yes, Planner boards and tasks associated with Teams are migrated with task assignments, due dates, checklists, and status preserved. The full Planner experience is transferred.

What about third-party apps in Teams?

Tabs pointing to third-party apps are recreated, but the actual app data may require separate migration or reconfiguration in the target tenant depending on the app.

Can I migrate specific Teams or channels?

Yes, you can select specific Teams or channels to migrate, allowing for granular control over your migration project. This is useful for phased rollouts or partial migrations.

Is there a free trial available?

Yes, Cloudiway offers a free trial so you can test the Teams migration with your own data before committing to a full project. No credit card required to start.

Are scheduled Microsoft Teams meetings preserved during a tenant-to-tenant migration?

Recurring and future-dated Teams meetings hosted by migrated users are re-created in the target tenant calendar with the original source Teams meeting links preserved. The target organizer can then edit the appointment, manually replace the source Teams meeting link with a new target Teams meeting link, and send the updated invitation to all attendees. Past meeting recordings stored in OneDrive or SharePoint are migrated alongside the rest of the file content, ensuring historical context remains accessible.
