Short answer
Yes, with third-party migration tools and some limits. Teams, standard channels, channel files and channel conversations can usually be migrated between tenants. One-to-one and group chats can be moved by several tools, though fidelity varies. Microsoft has no native end-to-end Teams migration between tenants, and some items, such as meeting recording links, apps and Loop components, need manual rework.
Key facts
- Microsoft does not offer a native end-to-end Teams migration between tenants.
- Channel files live in SharePoint and migrate like any document library.
- Migrated messages are recreated, so reactions, timestamps and author display depend on the tool.
- Private and shared channels have their own SharePoint sites and need separate mapping.
- Many organizations migrate recent chat history only and export older chats for retention.
What usually migrates
Third-party migration platforms use Microsoft Graph and related APIs to rebuild teams in the target tenant. Coverage differs by product, so confirm each item in a pilot.
| Item | Typical outcome | Notes |
|---|---|---|
| Team structure and membership | Migrates | Requires user mapping between tenants |
| Standard channel conversations | Migrates | Messages recreated, often with original timestamps and authors |
| Channel files | Migrates | Stored in the team's SharePoint site |
| Private channels | Usually migrates | Separate SharePoint site per channel |
| Shared channels | Limited | Cross-organization membership adds complexity |
| One-to-one and group chats | Often migrates | Fidelity and speed vary by tool |
| Tabs, apps, bots and connectors | Partial or manual | Usually reconfigured by hand |
| Meeting recordings and transcripts | Partial | Files move; links in chats may break |
| Planner plans | Tool dependent | Check coverage in pilot |
| Loop components | Limited | Often rebuilt or exported |
How Teams content is stored
Teams is a front end over several services. Channel files sit in a SharePoint document library. Private and shared channels each get their own SharePoint site. Files shared in one-to-one and group chats sit in the sender's OneDrive. Message content is stored in the Teams service, with compliance copies in Exchange Online.
That is why a Teams migration is really several migrations: SharePoint for channel files, OneDrive for chat files, and the Teams service for messages. Each needs to land in the right place, and file links inside messages need to point to the new location.
Limits to plan around
Even good tools cannot recreate everything exactly. Plan for these and tell users what to expect.
- Message throughput is throttled by Microsoft, so large chat histories take time and should be pre-staged.
- Reactions, edits, mentions and inline images may be simplified or flattened.
- Users in the old tenant who are not migrating, or external guests, may appear as plain names rather than linked accounts.
- Meeting chats tied to calendar events often need a different approach than normal group chats.
- Custom apps, Power Automate flows and Power Apps tied to a team must be rebuilt or re-pointed in the target.
- Retention, sensitivity labels and holds do not carry over automatically and must be set up in the target.
Deciding how much history to move
Moving every chat back to the first day of Teams use is rarely needed and adds time and tool cost. Common choices are to migrate channel content in full and limit chats to the last 6 to 24 months, or to migrate channels only and keep chats available through an export.
If records rules apply, coordinate with legal before deciding. Content under litigation hold or retention requirements may need to be preserved in the source tenant or exported with eDiscovery, regardless of what is migrated for daily use.
Running the Teams workstream
Teams migration works best after users and mailboxes are mapped and target accounts exist. Pre-stage channel content and files first, then run a delta close to cutover. Assign team owners in the target before users arrive so they can fix tabs and apps.
On cutover day, users sign in to the target tenant in the Teams client. Some will need to clear the client cache or add the new account. A short guide covering how to find old chats and pinned channels cuts help desk volume.
How Accred Consulting approaches it
Accred Consulting inventories every team, channel type, app and chat volume during discovery, then agrees with you what history to migrate and what to export. The proposal names the tooling, scope, fixed price and timeline. Our US-based specialists pilot Teams migration on real teams, confirm what moves cleanly and document anything needing manual rework, such as apps, tabs or flows. We stage content ahead of each wave, run deltas at cutover and hand over documentation and team owner guidance.
Track record: 400+ client projects, 2,000+ migration workstreams and 150,000+ users migrated by a US-based team. Company facts · Case studies
