Migrate Box to Microsoft 365 with Migration Manager

Collaborate all in one place by migrating your Box documents, data, and users to OneDrive, SharePoint, and Teams in Microsoft 365.

How does it work?

  • Step 1: Connect to Box. Sign in to your Box account and add the Microsoft 365 migration app to your Box account custom apps.
  • Step 2: Scan and assess Box user accounts are scanned automatically for you. Once the scans are complete, download the generated reports and logs to investigate any possible issues that might block your migration.
  • Step 3: Copy to Migrations list After a Box user has been scanned and determined ready, add them to your migration list.
  • Step 4: Review destination paths We automatically map source paths to any exactly matching destination paths. Ensure content is being copied to the right place by reviewing and modifying as needed for each destination path.
  • Step 5: Map identities Map your groups and users in Box to an account in Microsoft 365 to migrate your Box sharing settings.
  • Step 6: Migrate and Monitor After reviewing your migration setup, migrate your Box accounts and monitor the progress
