Legacy software modernization service refers to the process of updating or transforming outdated software systems to meet current technological standards and business needs. It involves reengineering, replatforming, or migrating existing applications to improve performance, scalability, and security. This service helps organizations reduce maintenance costs, enhance efficiency, and ensure compatibility with modern digital infrastructures.
The primary types of legacy software modernization services are application modernization, cloud migration, code refactoring, replatforming, database modernization, user interface modernization, and other related service types. Application modernization refers to the structured reengineering of legacy applications to enhance scalability, performance, security, and maintainability by updating architectures, decoupling monoliths, adopting modular patterns, introducing automated testing, and aligning functionality with current business requirements while minimizing disruption. The deployment modes include on premises, cloud based, and hybrid models, serving large enterprises and small and medium enterprises across banking, financial services and insurance, healthcare, government, manufacturing, retail, telecommunications, transportation and logistics, and other industry verticals.
Tariffs have created both challenges and opportunities for the legacy software modernization market by increasing the cost of importing servers, storage, and networking equipment required for on-prem modernization environments and testing labs. These cost increases can delay upgrade cycles for enterprises in North America and Europe that rely on Asia-Pacific supply chains for infrastructure components. Hardware-heavy segments such as private data center modernization, high-availability testing platforms, and migration staging environments are most affected due to higher capital costs and longer lead times. However, tariffs are also accelerating the shift toward cloud-based modernization, managed services, and software-defined infrastructure that reduces reliance on physical hardware. Vendors and service providers are expanding automation, improving security remediation tooling, and offering flexible delivery models to help customers modernize legacy software while controlling costs and reducing operational risk.

This legacy software modernization market research report delivers a complete perspective of everything you need, with an in-depth analysis of the current and future scenario of the industry.
The legacy software modernization market size has grown rapidly in recent years. It will grow from $15.14 billion in 2025 to $17.57 billion in 2026 at a compound annual growth rate (CAGR) of 16.1%. The growth in the historic period can be attributed to rising maintenance costs of legacy systems, increasing cybersecurity threats to outdated platforms, demand for better scalability and uptime, shift toward hybrid and cloud deployments, need for modernization to support new digital channels.
The legacy software modernization market size is expected to see rapid growth in the next few years. It will grow to $31.59 billion in 2030 at a compound annual growth rate (CAGR) of 15.8%. The growth in the forecast period can be attributed to adoption of cloud-based modernization services, increased use of container platforms, modernization driven by compliance audits, AI-assisted refactoring and testing, growth of managed modernization and support services. Major trends in the forecast period include database and middleware modernization, user interface and experience redesign, hybrid modernization roadmaps, security hardening for legacy apps, modernization with progressive refactoring.
The growing adoption of cloud-based platforms is expected to drive the growth of the legacy software modernization service market in the near future. Cloud-based platforms provide computing resources, storage, and applications over the internet, eliminating the need for local servers or devices. The adoption of these platforms is increasing due to their scalability, which enables flexible resource management, and their cost efficiency. Legacy software modernization services facilitate cloud adoption by transforming outdated systems into cloud-ready, scalable architectures that integrate seamlessly with modern cloud platforms, improving performance, flexibility, and business agility. For example, in January 2025, AAG IT, a UK-based IT services company, reported that an estimated 63% of small and medium-sized business (SMB) workloads and 62% of SMB data were expected to be hosted in public clouds by 2023, compared to 57% of workloads and 56% of data in 2022. This rise in cloud adoption is driving the growth of the legacy software modernization service market.
Leading companies in the legacy software modernization services market are focusing on developing AI-driven modernization applications to enable seamless migration of legacy systems to cloud-native architectures, improve operational efficiency, enhance scalability, and support digital transformation. AI-driven modernization apps use artificial intelligence to analyze, refactor, and transform legacy systems, facilitating faster migration to modern platforms, improving efficiency, and ensuring seamless integration with cloud and digital technologies. For instance, in October 2025, Red Hat, a US-based software company, introduced AI-powered tools designed to accelerate application modernization, particularly for enterprises with legacy codebases. These tools integrate with Red Hat's Migration Toolkit for Applications (MTA) to offer automated code analysis, refactoring suggestions, and guidance for migrating applications to cloud-native environments. This reduces manual effort, improves workflow efficiency, and speeds up the modernization process while ensuring compatibility with modern platforms and architectures.
In May 2024, Rocket Software, a US-based provider of enterprise software solutions, acquired OpenText's Application Modernization and Connectivity (AMC) business for $2.275 billion. This acquisition strengthens Rocket Software's legacy software modernization capabilities, expands its offerings in mainframe and legacy application modernization, and enhances its support for enterprise clients worldwide. OpenText's AMC business specializes in legacy software modernization services and is based in the US.
