Yes, SysInfo Microsoft SharePoint Migration Tool comes with a powerful built-in duplicate file removal feature that helps eliminate redundant SharePoint data before or during migration. Its advanced three-phase deduplication engine detects duplicate files using content hash, file names, file types, and creation dates, ensuring that only unique files are migrated to the destination tenant. This not only reduces storage consumption but also speeds up the migration process and keeps your SharePoint environment clean and organized. In addition to duplicate removal, the software supports Microsoft Graph API, Modern OAuth 2.0 authentication, incremental migration, intelligent site mapping, metadata preservation, and real-time progress reporting, making it a comprehensive solution for secure and efficient SharePoint tenant-to-tenant migrations on both Windows and macOS.
