About this tool
The OneDrive Migration tool enables direct tenant-to-tenant migration of OneDrive files with permission preservation. Transfer user files directly to target tenant OneDrive without intermediate storage.
Zero-knowledge architecture ensures files never pass through third-party servers. Direct Graph API transfers maintain file integrity, metadata, and sharing permissions where possible.
Includes delta sync for efficient large migrations and automatic conflict resolution.

Limitations & out-of-scope
Files.ReadWrite.All spans both reading the source drive and writing the target drive under one OAuth grant, the same single-app model as Mailbox Migration rather than the split source-read/target-write app pair Chat History Export uses. Permission preservation is best-effort — a sharing link or external-user grant with no equivalent identity in the target tenant cannot be recreated exactly, only approximated or flagged for manual review.
