Tenant-to-tenant migration of email, SharePoint, OneDrive, and Teams. Fully automated, monitored live at item level. No professional services. No per-seat licensing.
The migration engine processes multiple mailboxes concurrently with configurable concurrency per worker. Intelligent throttle management keeps every batch inside Microsoft Graph API rate limits automatically.
Built by engineers who've run large-scale M365 migrations. Every failure mode logged, retried, and recovered automatically.
Every mailbox, site, and drive shows live item counts, bytes transferred, and per-folder status. No black box — you see exactly what's happening.
Graph API failures are caught, logged, and retried with exponential backoff. Failed items requeue without halting the job.
SharePoint and OneDrive permissions, sharing links, and folder-level access controls faithfully mapped to the destination tenant.
Mailbox quota, SharePoint storage, and OneDrive allocation checked before a single item moves. Issues flagged at launch, not discovery.
OAuth 2.0 service principals only. No passwords stored. Content streams directly between tenants — never through our servers.
Automatic detection and back-off when hitting Microsoft rate limits. Maximises throughput without triggering 429s or service bans.
All four M365 workloads available now. Google Workspace and on-premises scheduled for Q4 2026.
Mailboxes, calendars, contacts, shared mailboxes, and distribution lists — with folder structure and read state preserved.
Site collections, document libraries, lists, pages, metadata, version history, and permissions.
Personal drives with folder structure, sharing links, and external share mappings intact.
Team workspaces, channels, message history, channel files, and 1:1 / group chat history independently.
Full migration from Google Workspace to Microsoft 365. Coming Q4 2026.
Migrate on-prem Exchange and file servers into M365. Coming Q4 2026.
Full discovery scan at no cost. Before any migration launches, we show you exactly how many tokens it will consume. No surprises.
For MSPs and IT consultancies running large-scale or repeated migrations across multiple tenants.
We migrated 340 mailboxes and 2 TB of SharePoint content over a weekend. Zero user complaints Monday morning. I didn't think that was possible.
The permission mapping on SharePoint is what sold us. We've tried other tools — the permissions always come out wrong. TheMigrator just handles it.
We're an MSP. We've run 60+ tenant migrations through this. The real-time logs and retry logic have saved us countless hours of manual work.
