How It Works

Four stages.
One engine.

Every migration follows the same fundamental workflow. What makes it work at enterprise scale is what happens inside each stage — resumable checkpointing, distributed execution, and the quiet refusal to stop when something goes wrong.

01 · DISCOVER

Know what you have before you move it.

The biggest migrations fail in the first week — because no one knew what was actually there. Discovery is the part everyone wants to skip. It's the part we refuse to.

We scan file systems, mailboxes, and archive stores across your environment. Every PST file, every mailbox, every archive is profiled: size, age, owner, content types, and known issues. You see exactly what needs to move before committing to a migration plan.

02 · ORCHESTRATE

Control what moves.
When. How fast.
By whom.

Enterprise migrations aren't one big push — they're thousands of small ones, sequenced carefully. Orchestration is where you stay in control of that complexity.

Queue jobs. Schedule migration windows around business hours. Assign agents to specific batches. Delegate sub-projects to regional IT teams with role-based access. Everything runs from one browser-based console with a full audit trail of who did what, when.

03 · MIGRATE

Move the data.
Survive what breaks.

This is the stage every other vendor gets wrong. When data is clean and the network behaves, migration is easy. When one message is corrupt at 3am on day 14, that's where tools prove themselves.

Distributed agents move data direct source-to-destination. Every message is checkpointed. Errors are classified: corrupt source items are logged and skipped, transient failures are retried, destination unavailability triggers pause-and-resume. A migration that fails at 87% resumes at 87% — not zero.

04 · VALIDATE

Prove every message made it.

"The migration is done" is not an answer for Legal. "Here is the reconciliation report showing every message accounted for" is. Validation is what lets you close the project.

Every action is logged: source item, destination location, timestamp, agent, result. Counts are reconciled source-vs-destination. Items that couldn't migrate (corruption, permission, policy) are reported explicitly with the reason. The audit trail is exportable in formats your regulators recognise.
