ServerBridge
File server → Microsoft 365 migration, done right.
A guided desktop wizard that helps IT professionals move on-premises file shares to SharePoint, OneDrive, and Teams — with real scanning, per-folder routing, and verification that checks Microsoft 365 itself.
Built for real migrations
Everything a file-server-to-Microsoft-365 move actually needs.
Guided 7-step wizard
Connect, scan, map, migrate, and verify — a clear path from file share to the cloud.
Real scan & analysis
A full inventory of your source — file counts, total size, structure and problem items — plus anything it couldn't read, listed rather than quietly skipped.
Per-folder routing
Send each top-level folder to its own SharePoint site, a Teams site, or a named person's OneDrive — so home folders land in their owners' drives. Migrating into someone else's OneDrive needs access granted first; ServerBridge checks up front and tells you exactly whose.
Resilient migration engine
Large files upload in chunks, with live progress, per-item logging and cancel at any time. Run the job again and it moves only what has changed since.
Verification & reporting
Reads every migrated file back from Microsoft 365 and compares it with the source, then exports a sign-off report that says what was confirmed — and what wasn't.
Secure by design
Delegated, least-privilege Microsoft Graph access. No passwords are ever stored.
Clean ROT data
Identify and trim redundant, obsolete, and trivial files before you migrate.
Planned · v2Permission review
Map source NTFS permissions to Microsoft 365 sharing and access before cutover.
Planned · v2The stack
A modern, cross-platform desktop app — Windows and macOS.
Clean separation of UI and business logic, an automated test suite, and security checks on every build.

Paying for Microsoft 365 licenses nobody uses?
The ServerBridge License Auditor cross-checks every assigned license against real sign-in activity and puts a dollar figure on the seats sitting idle. The scan is free, read-only and takes about five minutes.
Questions before you migrate?
