Legacy Modernization Market Report 2026

The legacy modernization market size has grown rapidly in recent years. It will grow from $22.17 billion in 2025 to $25.76 billion in 2026 at a compound annual growth rate (CAGR) of 16.2%. The growth in the historic period can be attributed to increasing operational and maintenance costs of legacy systems, growing business risk due to unsupported software, rising difficulty in finding legacy-skilled personnel, increasing regulatory and compliance requirements, and growing customer expectations for faster services.

The legacy modernization market size is expected to see rapid growth in the next few years. It will grow to $46.5 billion in 2030 at a compound annual growth rate (CAGR) of 15.9%. The growth in the forecast period can be attributed to increasing demand for digital customer experiences, growing pressure to reduce total cost of ownership, rising regulatory complexity and reporting requirements, increasing shortage of skilled information technology talent, and growing need for business agility and faster time. Major trends in the forecast period include advancements in cloud-native technologies, innovations in automated code transformation and refactoring tools, developments in containerization and orchestration platforms, research and development in artificial intelligence-driven migration assistants, and advancements in platform engineering and internal developer platforms.

The expansion of cloud-native and hybrid cloud deployments is expected to propel growth in the legacy modernization market going forward. Cloud-native and hybrid cloud deployments involve running applications that are fully optimized for cloud environments or distributed across a combination of on-premises and cloud infrastructures to achieve scalability, flexibility, and operational efficiency. This expansion is fueled by the increasing need for real-time, high-performance data processing and scalable applications. Legacy modernization strengthens IT ecosystems by enabling compatibility with cloud-native and hybrid cloud environments, making it well suited for organizations seeking improved scalability and flexibility. It also lowers operational complexity by facilitating seamless application and data migration, thereby improving efficiency and business agility. For example, in October 2025, according to the Cloud Native Computing Foundation, a US-based cloud native organization, 56% of backend developers were identified as cloud native in the third quarter of 2025, up from 49% in the first quarter of 2025, reflecting a notable increase over the past five years. As a result, the expansion of cloud-native and hybrid cloud deployments is driving the growth of the legacy modernization market.

Leading companies in the legacy modernization market are concentrating on the development of advanced platforms, such as AI-powered application modernization platforms, to improve efficiency, reduce technical debt, and accelerate innovation. AI-powered application modernization platforms are integrated solutions that apply artificial intelligence to analyze, refactor, and migrate legacy application code and data to modern architectures. For example, in September 2025, MongoDB Inc., a US-based database and enterprise software company, launched MongoDB AMP, an AI-powered application modernization platform. This comprehensive suite includes AI-driven tools such as a legacy code transpiler designed to accelerate the migration of legacy relational databases to MongoDB’s modern document-based platform. The platform features intelligent schema design and code conversion capabilities, enabling existing applications to align with flexible and scalable architectures while minimizing manual effort. It also provides analytics for dependency mapping and effort estimation, enhancing developer productivity and reducing operational costs and risks for enterprises.

In May 2025, TXP (Technology x People), a UK-based digital transformation and technology resourcing solutions provider, acquired Metatech Solutions Ltd. for an undisclosed amount. Through this acquisition, TXP aims to scale its digital transformation portfolio, strengthen its capabilities in automated Gen legacy modernization, and broaden its technology consulting and migration services for blue-chip clients across multiple industries. Metatech Solutions Ltd. is a UK-based company specializing in legacy system modernization and migration solutions.

The regions covered in the legacy 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 modernization market report are Australia, Brazil, China, France, Germany, India, Indonesia, Japan, Taiwan, Russia, South Korea, UK, USA, Canada, Italy, Spain.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

Tariffs have had a moderate impact on the legacy modernization market by increasing costs for imported software tools, middleware, databases, and on-premises hardware required during modernization projects. Service-heavy segments such as consulting, migration, and integration are less affected, while regions dependent on cross-border technology procurement, including Asia-Pacific and parts of Europe, face higher cost pressures. These impacts have encouraged enterprises to prioritize cloud-based deployments and locally sourced solutions. In some cases, tariffs have positively driven demand for software-only modernization and reduced reliance on hardware-intensive upgrades.

Legacy modernization refers to the process of updating or transforming outdated software systems, applications, or IT infrastructure to align with modern technologies, architectures, and platforms. Its primary objective is to enhance system performance, scalability, security, and maintainability while lowering operational costs and enabling support for evolving business requirements. This process commonly includes rehosting, refactoring, or replatforming legacy applications to ensure compatibility with current technological standards.

The primary components of legacy modernization include software and services. Software encompasses modernization platforms, tools, and automation technologies used to assess legacy systems, refactor outdated code, migrate applications to modern architectures, and improve system performance while retaining core business logic. Services include assessment, migration, integration, and maintenance offerings. Organizations adopting these solutions range from small and medium enterprises to large enterprises, with deployments implemented across on-premises and cloud environments.

The legacy modernization market consists of revenues earned by entities by providing services such as software redesign and redevelopment, legacy code analysis and optimization, API integration, modernization consulting, testing and quality assurance, and legacy system support and maintenance. The market value includes the value of related goods sold by the service provider or included within the service offering. The legacy modernization market also includes sales of modern software platforms, cloud-based solutions, development and modernization tools, middleware, databases, and application modernization frameworks. Values in this market are ‘factory gate’ values, that is the value of goods sold by the manufacturers or creators of the goods, whether to other entities (including downstream manufacturers, wholesalers, distributors and retailers) or directly to end customers. The value of goods in this market includes related services sold by the creators of the goods.

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).
