Microsoft Teams Tenant-to-Tenant Migration — Microsoft 365 Teams Data Move
IT Partner migrates your Microsoft Teams structure and documents from one Microsoft 365 tenant to another Microsoft 365 tenant. This service is typically used when a company merges or acquires another company, or when an organization wants to migrate to a different geographic region.
What this engagement is
This service plans, designs, and migrates Microsoft Teams from one Microsoft 365 tenant to a different Microsoft 365 tenant. The migration includes Teams and channels, files stored in Teams, channels inside Teams, and user membership information. The goal is to migrate Microsoft Teams data without loss of data, within an agreed time frame, and without downtime for users.
Success criteria
What you receive
How the work unfolds
Confirm business goals, source and destination tenant details, migration scope, key contacts, access requirements, expected timeline, and any known constraints such as licensing, naming standards, or cutover preferences.
Inventory the in-scope Teams, channels, owners, membership information, and files stored in Teams. Review the destination tenant readiness and confirm what will be migrated, what will be excluded, and any items that require client decisions before migration.
Create the agreed Teams and channel structure in the destination tenant and pre-stage supported file content where practical. This phase is used to reduce final migration time and identify access, naming, or data issues before the final migration event.
Validate that the destination Teams and channels are present, files are transferred as expected, and owner access has been provided. Review representative content and access with the client point of contact before proceeding to final migration.
Complete the final migration pass for in-scope Teams content, confirm the destination environment is accessible, and provide a final status summary including any known exceptions or client follow-up items such as membership management or desktop client reconfiguration.

Frequently asked questions
What does IT Partner’s Microsoft Teams tenant-to-tenant migration service do?
IT Partner migrates Microsoft Teams from one Microsoft 365 tenant to another Microsoft 365 tenant. The service is typically used for mergers, acquisitions, or moves to a different geographic region, because it transfers Teams structure and documents into the destination tenant.
What is included in the Microsoft Teams tenant-to-tenant migration?

IT Partner also identifies source Teams data, creates the appropriate team and channel structure in the destination tenant, transfers files, and provides owner access to all Teams in the destination tenant.
What is not included in this Teams migration service?
The service does not include informing users about upcoming changes or changing desktop software settings. If Microsoft Teams desktop clients need reconfiguration for connectivity to Microsoft 365, that is listed as the client’s responsibility.
How long does a Microsoft Teams tenant-to-tenant migration take?
The exact plan may vary depending on your needs, because the source scope and migration requirements can differ by tenant.
How is this Teams migration service priced?
The final cost depends on the amount of data migrated, because the service includes a per-gigabyte component.
What access is required before the migration can begin?
You must provide global admin-level access to both the source Microsoft 365 tenant and the destination Microsoft 365 tenant. The destination tenant must also have Teams licensing available, because users need to access Microsoft Teams in the destination environment.
Will users experience downtime during the Teams migration?
The stated goal and success criteria are to migrate Microsoft Teams data without data loss, within the agreed time frame, and without downtime for users. Specific scheduling and validation should be confirmed with IT Partner during planning, because the migration plan may vary based on client needs.
What happens during the Teams tenant-to-tenant migration engagement?
The engagement is organized around kickoff, determining source data, pre-stage migration, migration validation and access provision, and final data migration. These milestones support identifying Teams, channels, and files in the source tenant, creating the destination structure, transferring files, and validating access.
Who is responsible for managing the migration work?
IT Partner is responsible for identifying source Teams data, creating the destination team and channel structure, transferring files, and providing owner access to all Teams in the destination tenant. The client is responsible for providing a dedicated point of contact, coordinating outside vendors if needed, reconfiguring Teams desktop clients if used, and managing user membership in Teams.
Does the service migrate files stored in Microsoft Teams?
Yes. The service includes transfer of files stored in Teams and channels from the source tenant to the destination tenant.
Does the service recreate Teams and channels in the destination tenant?
Yes. IT Partner creates the appropriate team and channel structure in the destination tenant as part of the migration, based on the Teams and channels identified in the source tenant.
Does the service migrate user membership information?
Yes, migration of user membership information is included in the stated deliverables. Ongoing management of user membership in Teams is listed as the client’s responsibility, so membership requirements should be reviewed during the engagement.
Will users be able to access Teams after the migration from different devices?
Yes. A success criterion is that users can access Microsoft Teams in the destination tenant from desktop PCs, mobile phones, and tablets from any place, at any time.
What happens after the Teams migration is completed?
After completion, the Teams, channels, and files should be available in the destination tenant, and owner access is provided to all Teams in that destination tenant. The client remains responsible for user communications, desktop client reconfiguration if required, and ongoing Teams membership management.
Does this service include user communications about the migration?
No. Informing users about upcoming changes is explicitly not included in the service, so the client should plan and send any user communications.
Does this service configure Microsoft Teams desktop clients for users?
No. Desktop software settings are not included, and reconfiguring Microsoft Teams desktop clients for connectivity to Microsoft 365 is listed as the client’s responsibility if those clients are used.
Does this service migrate Teams chat history, apps, tabs, Planner, meetings, or other Teams-connected workloads?
Those items are not listed in the stated scope. The documented scope covers Teams, channels, files stored in Teams, channels inside Teams, and user membership information, so any requirement for chat history, apps, tabs, Planner, meetings, or other connected workloads should be confirmed with IT Partner before purchase.
Can the migration plan be customized?
Yes, the service notes that the plan may vary depending on your needs. The core service remains a Microsoft Teams tenant-to-tenant migration, but the exact approach and sequencing should be confirmed with IT Partner during kickoff and planning.
