Box Migration Tool

MigrationFox migrates files, folders, and collaborations from Box.com to any supported destination. Whether you're consolidating onto Microsoft 365, moving to Google Workspace, or archiving to S3, MigrationFox handles Box's quirks — chunked uploads, collaboration roles, and long path limits — automatically.

Chunked Upload Handling

Box enforces a hard 20 MB limit on single-request uploads. Files larger than that must be split into chunks and assembled server-side. MigrationFox manages this transparently: files above the threshold are uploaded in parallel 8 MB chunks with automatic retry on per-chunk failure.

On the read side, downloads from Box use range requests with streaming to avoid buffering entire files into memory. Large files flow straight through to the destination without touching local disk.

Collaboration Migration

Box organizes sharing through collaborations — named roles like Viewer, Editor, Co-owner, and Previewer attached to folders and individual files. MigrationFox reads every collaboration on each item during the transfer phase and maps the role to the destination platform's equivalent:

• Previewer / Viewer → Read access
• Editor → Write / Contribute access
• Co-owner / Owner → Write / Full Control (where supported)
• Uploader → Logged to skipped-items report — no direct equivalent on most destinations

Supported Migration Paths

Box to SharePoint

The most common Box migration. Folders become document libraries, collaborations become SharePoint permissions, and file paths are sanitized to fit SharePoint's 400-character limit.

Box to OneDrive

Move personal Box accounts or small team folders to individual OneDrive for Business accounts during an M365 rollout.

Box to Google Drive

Transfer Box content to Google Shared Drives with folder structure and sharing preserved.

Box to Amazon S3

Archive Box content to S3 for compliance or long-term cold storage. Original metadata is stored alongside each object as S3 user metadata.

Key Features

• Enterprise JWT auth — service account access without per-user login flows
• Parallel folder scan — 8 concurrent folder traversals for fast discovery
• Metadata preservation — Box file descriptions and tags are carried over where the destination supports them
• Version handling — only the current file version is transferred by default (full version history available on request)
• Delta sync — re-run jobs move only files modified since the last run

Pricing

Box migrations are billed at $0.50 per GB transferred. Your account starts with 2 GB free — no credit card required. Discovery scans are always free and unlimited.
