Zero-Downtime Migration

Keep legacy and modern environments perfectly aligned — with zero footprint.

DataSync is a stateless, event-driven synchronization engine. It forms a persistent data bridge between source and target so you can migrate users in phases without split-brain issues, auth failures, or broken sessions.

Architectural capabilities

Stateless Event Processing Pipeline

Operates completely stateless. DataSync triggers exclusively on event changes (e.g., user sign-up, password reset, profile modification), minimizing data-at-rest exposure while keeping target boundaries entirely up to date.

Multi-Source Aggregation & Merging

Consolidate multiple distributed user directories into a single unified target. DataSync intercepts duplicate events across disparate systems, matches records using rules-driven deterministic logic, and presents a clean, single-identity profile to the destination system.

Resilient Enterprise Plumbing

Outfitted with heavy-duty enterprise resilience frameworks. Features dedicated message queuing backups, live streaming performance monitors, structured error handling tables, and high-fidelity auditable logs.

Use case spotlight — Phased enterprise cutover

For large-scale web ecosystems, an instant, single-moment shift is impossible. DataSync forms a persistent data bridge, allowing groups of users to be migrated smoothly over weeks. During this interim, modifications made on either side sync instantly across systems — preventing split-brain issues, auth failures, and broken sessions.
