The Problem

Cloud migrations don't fail loudly.
They fail silently.

A migration that misses 2% of messages still finishes "successfully." You find out months later, when Legal asks for the missing emails and they're gone.

80%

of users have corrupt messages

in their Enterprise Vault archive. Native tools stop at the first corruption. We log, skip, and keep going — and give you a report of what couldn't come across.

2-stage migrations waste weeks

Most tools force PST as an intermediate hop. We move data source-to-destination in a single orchestrated pass — no intermediate files, no data exposed in transit.

Restart means re-copy

When standard tools fail at 3am on day 12, they restart from zero. Ours resume from the last successful message. No duplicates. No lost weekend.

No audit trail = failed audit

If you can't prove chain of custody, the migration didn't happen — as far as your auditor is concerned. Every action we take is logged, timestamped, and exportable.

The Engine

One engine.
Every path into the cloud.

From PSTs hiding on laptops to petabyte journal archives in Enterprise Vault — Cloud2Cloud Migrator orchestrates every migration path through a single console, with distributed agents doing the heavy lifting.

PST Migration

Find the PSTs nobody admits to having. Auto-assign owners. Migrate directly into Microsoft 365, Enterprise Vault, or Mimecast. Kill the GDPR liability sitting on laptops.

Archive Migration

Pull data out of Enterprise Vault, Mimecast, Symantec.cloud, and public folders into Microsoft 365. Folder structure, metadata, and chain of custody preserved.

Explore Archive Migration →

Enterprise Vault Migration

Retire Enterprise Vault without losing a message. Personal archives, journal archives, shortcuts, and public folders — all handled by a single engine.

Shortcut Rehydration

Recall archived messages directly in Microsoft 365 or Exchange. Only the shortcuts the user still has get rehydrated — nothing unexpected reappears.

How It Works

Discover. Orchestrate.
Migrate. Prove.

Four stages. One engine. Every stage is resumable, auditable, and runs at enterprise scale.

01

Discover

Scan file systems, mailboxes, archives. Profile what's there.

02

Orchestrate

Queue, assign owners, schedule migration windows.

03

Migrate

Distributed agents move data direct source-to-destination.

04

Validate

Verify counts, produce the audit trail, reconcile.

Distributed Architecture

Central console.
Agents where you need them.

Scale throughput by adding agents. Manage everything from one browser-based console — accessible from anywhere, including your phone at 11pm.

Why Cloud2Cloud Migrator

Built for the migrations
that go wrong.

Any tool can move clean data. The real test is what happens on day 14 when something breaks.

Resumable by design

Every message tracked. A failed migration resumes from the last successful item — not from zero. No duplicates, no re-scans.

Fault-tolerant by default

Corrupt messages are logged and skipped, not fatal. Migrations complete even when source data is broken.

Direct source-to-destination

No PST intermediate step. Data moves straight from Enterprise Vault, Mimecast, or public folders into Microsoft 365.

Distributed agents

Scale throughput by adding agents. Central console manages everything from one browser, from anywhere.

Full chain of custody

Every action logged. Every message accounted for. Auditable reporting that stands up to regulators and Legal.

Proven at petabyte scale

165 TB. 90,000+ mailboxes. US and Australian governments. Not chasing enterprise — we started there.
