Modernize Without the Risk

Legacy system migrations, containerization, and cloud-native transformations. Zero-downtime moves that don't disrupt your business.

Risk-managed, value-led modernization

The migration playbook
that protects production.

Legacy systems are holding you back. On-premise servers are expensive, monolithic apps can't scale, and outdated technology makes hiring harder. But modernization projects are notorious for delays, cost overruns, and failed launches.

We've completed 30+ migrations with zero unplanned downtime. Our approach prioritizes risk mitigation, thorough planning, and incremental execution — so you get the benefits of modern infrastructure without the horror stories.

Transformation services

From on-prem workloads to monoliths to legacy databases — moves designed to land without surprises.

On-Premise to Cloud

Move from data centers to AWS, GCP, or Azure. Lift-and-shift or re-architecture based on your goals.

Containerization

Package applications into containers. Docker, Kubernetes, and container orchestration at scale.

Monolith to Microservices

Break apart monolithic applications into scalable microservices architecture. Strangler fig pattern for safe transitions.

Database Migrations

Move from Oracle to PostgreSQL, SQL Server to Aurora, or any database modernization with zero data loss.

Data Warehouse & Analytics

Move legacy warehouses and Hadoop estates onto modern stacks—Redshift, Aurora, S3-backed lakes, and lakehouse patterns—without breaking the dashboards downstream.

Cloud-to-Cloud & Repatriation

Move workloads between hyperscalers or back from a misfit cloud. Azure or GCP to AWS, multi-cloud rebalancing, and clean exit paths—runbook-led, never rushed.

Our Approach

Risk-first migration methodology

No surprises on cutover day. Every step has a runbook, a rollback, and a measurable exit criterion.

01
Weeks 1–2

Discover

Map dependencies, assess risks, and understand the full scope of what needs to move.

02
Weeks 2–4

Plan

Create detailed runbooks, rollback procedures, and a phased migration schedule.

Execute

Migrate incrementally with extensive testing. Blue-green deployments and canary releases.

Optimize

Post-migration optimization, cost tuning, and decommissioning of legacy systems.

Compliance survives the move

Migrations that keep your audit trail, your data residency, and your regulator-facing controls intact across the cutover — not retrofitted on the other side under deadline pressure.

Data Residency & Sovereignty

EU-region landing zones, customer-managed keys, and architecture choices that keep data, control plane, and operator access inside the boundary your regulator or your customer requires.

Audit-Continuity Plan

Logging, evidence pipelines, and control attestations that span both sides of the cutover. Your SOC 2 or ISO 27001 cycle doesn't gap, and the auditor sees one consistent story.

GDPR-Aware Data Migration

Data classification, DPIA-aligned residency, encryption in transit and at rest, and key custody preserved through every hop. Personal data never lands where it shouldn't.

DORA & NIS2 Continuity

Exit-path evidence, third-party-register updates, and resilience-testing rehearsals on the new estate—so DORA and NIS2 supervisors see a smooth, documented transition.

Zero-Downtime Cutover Discipline

Blue-green, canary, and dual-write patterns that keep the customer-facing path live throughout the move. Cutover day is observable, reversible, and boring by design.

Modernised, Not Re-Hosted

Lift-and-shift only where it pays. Containerisation, managed services, and serverless adoption where the post-migration bill, posture, or velocity actually improves.
