Legacy Application Modernization Market Report 2026

The legacy application modernization market size has grown rapidly in recent years. It will grow from $19.16 billion in 2025 to $21.94 billion in 2026 at a compound annual growth rate (CAGR) of 14.5%. The growth in the historic period can be attributed to aging application portfolios and technical debt, data center exit initiatives, demand for faster release cycles, shortage of legacy skillsets, increasing security and compliance requirements.

The legacy application modernization market size is expected to see rapid growth in the next few years. It will grow to $37.33 billion in 2030 at a compound annual growth rate (CAGR) of 14.2%. The growth in the forecast period can be attributed to migration to cloud-native architectures, adoption of event-driven integration, increased use of automation for code conversion, modernization driven by AI-assisted development, growth of hybrid integration and platform engineering. Major trends in the forecast period include microservices refactoring programs, containerization and kubernetes migration, api-first integration modernization, low-code assisted modernization, devsecops and automated testing adoption.

The increase in government digital transformation initiatives is expected to drive the growth of the legacy application modernization market going forward. Government digital transformation initiatives are coordinated public-sector programs aimed at digitizing services and operations by upgrading legacy systems, adopting cloud platforms, standardizing identity and payments, and enhancing user experience and security. The rise in these initiatives is driven by policy mandates to consolidate and modernize legacy systems to deliver secure, scalable online public services. Legacy application modernization enables agencies to rebuild or replatform outdated systems, expose data and functions through application programming interfaces, and connect them to shared identity, payments, and cloud platforms, turning policy directives into resilient digital public services delivered faster. For instance, in August 2023, GOV.UK, a UK-based federal government agency, reported that GOV.UK Pay onboarded 163 services in the previous 12 months and processed 23 million payments in the last financial year, highlighting the accelerating adoption of government digital platforms. Therefore, rising government digital transformation initiatives are fueling the growth of the legacy application modernization market.

Major companies in the legacy application modernization market are focusing on innovation, including comprehensive modernization portfolios that provide end-to-end solutions for updating legacy systems, integrating advanced technologies, enhancing compliance, and improving efficiency. Comprehensive modernization portfolios are complete sets of tools and services designed to upgrade, transform, and optimize legacy applications and systems. For example, in September 2025, MongoDB, Inc., a US-based software company, launched the AI-Powered Application Modernization Platform to reduce technical debt and accelerate innovation. The platform combines AI-driven tools, a proven delivery framework, and expert engineers to speed up code transformation and overall modernization projects. Legacy applications often limit innovation and pose security and compliance risks due to rigid data foundations and outdated architectures. MongoDB AMP addresses these challenges by enabling full-stack modernization, reducing technical debt, improving speed-to-market, and supporting innovation while lowering costs.

In January 2023, OpenText Corporation, a Canada-based information management software company, acquired Micro Focus International plc for an undisclosed amount. Through this acquisition, OpenText aimed to expand its legacy application modernization capabilities by leveraging Micro Focus’s strengths in COBOL tooling, host connectivity, testing, and mainframe modernization, helping customers transition from aging platforms to more secure, scalable, and cloud-ready architectures with greater speed and lower risk. Micro Focus International plc is a UK-based enterprise software company.

Major companies operating in the legacy application modernization market are Microsoft Corporation, Deloitte Consulting LLP, Accenture plc, International Business Machines Corporation, Tata Consultancy Services Limited, Fujitsu Limited, Capgemini SE, Cognizant Technology Solutions Corporation, Infosys Limited, HCL Technologies Limited, DXC Technology Company, Atos SE, Wipro Limited, Tech Mahindra Limited, Bell Integrator LLC, Blu Age SAS, EvolveWare Inc., The Software Revolution Inc., Semantic Designs Inc., Expersolve Inc.

North America was the largest region in the legal application modernization market in 2025. Asia-Pacific is expected to be the fastest-growing region in the forecast period. The regions covered in the legacy application modernization market report are Asia-Pacific, South East Asia, Western Europe, Eastern Europe, North America, South America, Middle East, Africa. The countries covered in the legacy application modernization market report are Australia, Brazil, China, France, Germany, India, Indonesia, Japan, Taiwan, Russia, South Korea, UK, USA, Canada, Italy, Spain.

Tariffs have created both challenges and opportunities for the legacy application modernization market by increasing the cost of importing servers, storage, networking equipment, and modernization lab infrastructure used for migration and testing environments. These cost increases can slow large-scale transformation programs for enterprises in North America and Europe that depend on Asia-Pacific supply chains for IT hardware refresh cycles. Hardware-heavy segments such as on-prem modernization staging environments, performance testing infrastructure, and mainframe connectivity appliances are most affected due to higher capital costs and longer lead times. However, tariffs are also accelerating adoption of cloud migration, platform-as-a-service modernization, and software-based automation that reduces dependency on physical infrastructure. Service providers are enhancing tooling, improving DevSecOps practices, and offering managed modernization programs to help customers reduce risk and control costs while upgrading mission-critical systems.

Legacy application modernization is the process of updating or transforming older software systems to align with current technologies, architectures, and practices. Its key purpose is to enhance performance, scalability, and maintainability while preserving core business logic and functionality. This approach helps organizations reduce technical debt, lower operational risks, and improve long-term adaptability.

The key types of legacy application modernization are application re-platforming, application re-hosting (lift and shift), application re-architecting, application re-engineering, and other supporting service types. Application re-platforming involves moving an existing application to a new runtime or cloud platform with minimal, targeted changes to leverage modern services, improve scalability, and run more efficiently. Modernization employs technologies such as artificial intelligence (AI) and machine learning (ML), robotic process automation (RPA), cloud computing, big data and analytics, Internet of Things (IoT), and blockchain, and is applied across organization sizes, including small and medium-sized enterprises (SMEs) and large enterprises. These modernized applications are used in cloud applications, on-premise applications, mobile applications, and web applications, and serve end users across sectors such as banking, financial services, and insurance (BFSI), healthcare and life sciences, information technology (IT) and telecom, retail and e-commerce, and others.

The legacy application modernization market includes revenues earned by entities by providing services such as application portfolio assessment and road-mapping, rehosting (lift-and-shift), replatforming, refactoring or recoding, rearchitecting to microservices and containers, application programming interface enablement and systems integration. The market value includes the value of related goods sold by the service provider or included within the service offering. Only goods and services traded between entities or sold to end consumers are included.

The market value is defined as the revenues that enterprises gain from the sale of goods and/or services within the specified market and geography through sales, grants, or donations in terms of the currency (in USD unless otherwise specified).
