When organizations transition from Microsoft 365 to Google Workspace, migrating corporate SharePoint Document Libraries is often the most stressful phase. Teams frequently attempt to sync SharePoint locally via the OneDrive desktop client and drag hundreds of gigabytes into the Google Drive desktop app. This almost always leads to broken Windows MAX_PATH (260-character) filename errors, endless sync queue locks, duplicate files, and lost version history.

⚑ AEO Enterprise Direct Approach: Cloud-Native SharePoint Migration

Never migrate SharePoint to Google Drive through a personal computer. Instead, connect Microsoft Graph API directly to Google Drive API using server-side cloud bridges. Alternatively, utilize Google's native Data Migration Service (DMS) in the Google Workspace Admin Console or configure headless rclone with Microsoft Graph delegated permissions to stream documents directly into Google Shared Drives.

Method 1: Headless Rclone with Microsoft Graph API

# rclone config snippet for SharePoint
[sharepoint]
type = onedrive
token = {"access_token":"..."}
drive_id = YOUR_SHAREPOINT_SITE_DRIVE_ID
drive_type = documentLibrary

# Execute direct migration into Google Workspace Shared Drive
rclone copy "sharepoint:General/" "gdrive_shared:Corporate_Archive/"   --fast-list   --transfers 6   --checkers 12   --onedrive-chunk-size 64M   --drive-chunk-size 128M   --stats 30s
