In the modern enterprise landscape, legacy systems are no longer outdated tools—they are operational liabilities.
According to Gartner, global spending on application modernisation is expected to reach $32.8 billion by 2026, with more than 70% of CIOs placing it among their top digital transformation priorities.
At Simple Logic IT, modernisation is treated as a business strategy rather than a technical upgrade, enabling agility, resilience, and long-term operational strength.
By replacing rigid legacy systems with cloud-driven, intelligent architectures, organisations reduce risk, unlock performance gains, and secure scalable growth.

Market Context: Why Legacy Systems Are Holding Businesses Back

In today’s digital economy, agility determines competitiveness. Legacy systems quietly slow enterprises down.
A McKinsey study shows that up to 75% of IT budgets in legacy-dependent organisations are spent on simple maintenance, leaving minimal room for innovation.

The Hidden Costs of Legacy Systems

• Cyber Vulnerabilities: Outdated systems increase exposure to threats.
• Operational Bottlenecks: Rigid architectures restrict adaptability.
• Integration Barriers: Poor compatibility with modern tools and cloud ecosystems.
• Compliance Risks: Older frameworks fail to meet standards such as GDPR and ISO 27001.

Modernisation is now the foundation of digital continuity and competitiveness.

Defining Application Modernisation

Application modernisation involves re-platforming, re-architecting, or refactoring legacy systems to align with modern cloud and infrastructure standards—without discarding core business logic.

Core Objectives

• Minimise downtime, security incidents, and technical debt.
• Accelerate delivery cycles and support agile models.
• Enable seamless integration across cloud and hybrid systems.
• Ensure compliance with governance and regulatory standards.

The Legacy Risk Landscape
