Eliminating Risk in a National Data Platform

Client Overview

A national-level government agency in the United Arab Emirates, responsible for delivering critical citizen-facing services across multiple regions.

The platform underpinned essential public services, where performance, data integrity, and system availability were directly linked to citizen experience and operational continuity at a national level.

While not operating at hyperscale, the platform had reached a level of complexity and demand where stability and reliability were non-negotiable.

Why Ordinis Linea

The agency required more than a technical migration partner, it needed a delivery team capable of taking control of a fragmented, high-risk environment where failure was not an option.

Ordinis Linea was selected for our ability to operate in complex, sensitive environments where data integrity, service continuity, and accountability are critical. Our approach focused on removing uncertainty, establishing full visibility, and ensuring that every stage of the migration could be executed and validated without risk to live services.

Key factors in the decision included:

• A structured, risk-first approach to migration, prioritising data integrity and continuity of service

• Experience working with legacy, undocumented environments where clarity had to be established before change

• Strong emphasis on control, traceability, and validation throughout the migration lifecycle

• The ability to design and execute zero-risk transition strategies, including parallel run and rollback capability

• A focus on leaving the organisation with full ownership, documentation, and operational independence

• This gave the agency confidence that the migration would not introduce further instability, and that the platform would emerge in a controlled, fully understood, and sustainable state.

The Challenge

The agency’s core system was built on a legacy SQL-based environment that had not evolved in line with increasing service demand.

Over time, performance degradation, data inconsistencies, and recurring outages began to impact service delivery. Previous attempts to modernise parts of the system had introduced fragmentation, resulting in multiple data sources, undocumented dependencies, and a lack of overall control.

Internal teams were managing increasing operational risk, with limited visibility and high reliance on a small number of individuals with legacy knowledge.

Key issues included:

• Data inconsistencies across systems

• Increasing latency under load due to unoptimised queries

• No clear rollback or structured migration strategy

• High dependency on a small number of individuals

• Risk of service disruption affecting citizens

Our Approach

Ordinis Linea was engaged to take full ownership of both the migration and stabilisation of the platform, addressing the underlying technical challenges while restoring operational control.

We began by establishing complete clarity across the database estate, identifying dependencies, mapping data flows, and documenting previously undocumented components that posed a risk to migration.

A controlled migration strategy was then designed to ensure continuity of service, with a strong emphasis on eliminating risk during transition.

Our work included:

• Conducting full database estate discovery and dependency mapping with detailed documentation

• Designing and executing a controlled migration from legacy SQL systems to the latest MariaDB version

• Building a parallel run environment using blue/green deployment to eliminate cutover risk

• Rewriting and optimising critical queries for performance within MariaDB

• Implementing robust data validation and reconciliation frameworks

• Introducing monitoring, backup, and failover mechanisms

• Delivering comprehensive documentation and structured operational handover

This approach ensured that the migration was not only technically successful, but fully understood and sustainable by the internal team.

The Outcome – Before vs After

Before

• Data inconsistencies across multiple systems

• Increasing latency and degraded performance under load

• No safe rollback or migration approach

• High reliance on individuals with legacy knowledge

• Ongoing risk to citizen-facing services

After

• Consistent, validated data across the platform

• Improved query performance and system responsiveness

• Controlled, risk-free migration with full rollback capability

• Reduced dependency on individuals through documentation and structure

• Stable platform supporting critical national services

Key Results

• An average of 20% improvement in query performance, with some cases achieving 60–100% improvement

• Zero data loss during migration

• Fully stabilised platform supporting national services

• Reduced operational risk and reliance on individual knowledge

• Internal team enabled to independently manage and support the environment

Commercial and Operational Impact

This engagement delivered more than a database migration.

The agency was able to:

• Safeguard continuity of critical citizen services

• Restore confidence in platform reliability at leadership level

• Reduce operational overhead and reactive support effort

• Establish a structured, maintainable, and future-ready data environment

• Enable internal teams to operate with clarity and control

Summary

The platform moved from a fragmented, high-risk environment to a stable, controlled system capable of supporting national services with confidence.

Ordinis Linea did not simply migrate databases.

We removed a critical point of failure, restored data integrity, and re-established operational control at a national level.
