Mian Points: 

  • Microsoft has introduced a Slack-to-Teams migration tool within the Microsoft 365 admin center. 
  • The tool enables easy transfer of channels, messages, files, and memberships to Teams with minimal effort. 
  • Initially, the migration tool focuses on moving channel content. 

Microsoft is making it easier to switch from Slack to Teams with a new migration tool built directly into the Microsoft 365 admin center. This feature simplifies the transfer of channel content, helping businesses consolidate collaboration without the usual challenges of platform migration. 

With this tool, customers can migrate data from their Slack workspace to Microsoft Teams, including: 

  • Public and private Slack channels 
  • Channel messages 
  • File attachments 
  • Canvas and list content 
  • Channel memberships (owners and members) 

According to Microsoft, “The migration tool runs within the Microsoft 365 admin center and uses Slack export packages along with online access to the customer’s Slack workspace to retrieve data. Customers generate Slack export packages through the standard Slack workspace administration interface.” 

How IT Admins Can Use the Slack-to-Teams Migration Tool 


IT administrators will find the migration tool under the Migration and Imports page in the Microsoft 365 admin center. From the setup page, they can upload a Slack export file and choose the workspace to migrate. Admins can also run migration tasks and track their progress directly on the migration dashboard. 

Microsoft notes that this feature will be enabled by default. IT admins can review which Slack channels qualify for migration before proceeding. At launch, the tool supports migrating channel messages, with future updates expected to include additional Slack content types. 

Guidance for IT Admins: Simplifying Migration and Preparing for Transition 


For IT administrators, this integrated Slack-to-Teams migration tool simplifies cross-platform consolidation by identifying eligible Slack channels and guiding content transfer directly within the Microsoft 365 admin center. It also offers task execution and status tracking, reducing manual work and eliminating the need for custom scripts. 

Admins should plan change-management communications and ensure helpdesk readiness before deployment, while aligning channel mappings (public/private/shared) with Teams governance policies. They should also verify compliance and retention settings to guarantee migrated conversations adopt the correct Teams policies and audit trails. 

Microsoft confirmed that this tool is currently in public preview for targeted release customers, with general availability for all commercial customers expected in March 2026. Additional details on completing the migration process can be found on the official support page.
