As the word \u201clegacy\u201d implies, such systems were once important assets supporting companies\u2019 core operations. However, they often cannot adapt to today\u2019s rapidly changing business environment and technologies, making them a major obstacle to DX (digital transformation) for many companies.<\/p>\n\n\n\n<p>After years of operation and repeated partial modifications, many legacy systems have become highly complex and internally opaque. As a result, maintenance and operations workloads have grown sharply, while incident response and adding new features now require substantial time and cost.<\/p>\n\n\n\n<p>According to the DX Trends Survey by the Information-technology Promotion Agency, Japan (IPA), more than 60% of Japanese companies (61%) still have legacy systems, highlighting how these systems hinder DX initiatives.<\/p>\n\n\n\n<p>To avoid risk of system trouble, rising security risks, and concerns over business continuity, moving away from legacy systems is urgent priority for companies. Strategic approaches such as \u201cmodernization\u201d and \u201clegacy migration,\u201d discussed in detail in next chapter, are essential to solving this issue.<\/p>\n\n\n\n<h3 class=\"wp-block-heading smile-subheading\">What is modernization?<\/h3>\n\n\n\n<p>Modernization is an initiative to align aging legacy systems with today\u2019s business needs through advanced IT technologies and strategic approaches. Rather than merely \u201creplacing\u201d systems, it aims to dramatically improve productivity, flexibility, and security across the entire system while making full use of the business assets and know-how that companies have built over many years.<\/p>\n\n\n\n<p>Typical modernization targets include core systems on mainframes or proprietary operating systems introduced in the 1980s, as well as systems developed in older programming languages such as COBOL. Open systems introduced from the late 1990s onward may also be candidates if they cannot adequately support today\u2019s technology trends, such as cloud computing and API integration.<\/p>\n\n\n\n<p>\u201cModernization\u201d derives from English words meaning \u201cto make modern\u201d or \u201cto update for present day.\u201d In IT, it is often referred to as \u201cIT modernization\u201d or \u201csystem modernization.\u201d In recent years, \u201cmodernize\u201d has also become widely used as verb, and modernization is now recognized as essential element for companies pursuing DX (digital transformation).<\/p>\n\n\n\n<p>Against this backdrop, modernization is no longer merely technical renewal; it has become key pillar of corporate strategy. It is highly strategic investment that combines both \u201coffense,\u201d enabling companies to respond flexibly to future changes in business environment while preserving existing strengths, and \u201cdefense,\u201d reducing risk and maintaining stability.<\/p>\n\n\n\n<h3 class=\"wp-block-heading smile-subheading\">Difference Between Modernization and Migration<\/h3>\n\n\n\n<p>When considering a move away from legacy systems, companies generally have two main approaches: modernization and migration. These methods may appear similar at first glance, but they differ clearly in purpose, method, and expected outcomes. To choose the best option for your organization, it is essential to understand these differences accurately.<\/p>\n\n\n\n<p>The table below clearly compares the main differences between modernization and migration.<\/p>\n\n\n<div class=\"smile-table-wrap\"><table class=\"smile-comparison-table\"><thead><tr><th scope=\"col\">Item<\/th><th scope=\"col\">Modernization<\/th><th scope=\"col\">Migration<\/th><\/tr><\/thead><tbody><tr><th scope=\"row\">Overview<\/th><td>Use existing assets to adapt systems to the latest technologies and environments, then strengthen and optimize them<\/td><td>Moving old systems or data to a new environment. The focus is on relocation, generally without changing functions or structure.<\/td><\/tr><tr><th scope=\"row\">Purpose<\/th><td>Respond flexibly to changing business requirements and market needs while improving functionality, performance, and maintainability<\/td><td>Main goals are to address aging environments and end of support, strengthen security, and reduce operating costs.<\/td><\/tr><tr><th scope=\"row\">Scope of Change<\/th><td>Make wide-ranging changes to system structure, code, UI\/UX, business processes, data structures, and more<\/td><td>Primarily changes infrastructure or platforms while generally preserving application logic<\/td><\/tr><\/tbody><\/table><\/div>\n\n\n<p>Modernization and migration each have different strengths and characteristics. To advance DX and drive business growth, companies must assess current state of their legacy systems, target business strategy, available human resources, cost outlook, and other factors holistically, then choose most effective and realistic approach.<\/p>\n\n\n\n<p>At SMILE, we conduct detailed analysis of current state of your legacy systems and recommend, based on deep experience and expertise, whether modernization, migration, or combination of both is best fit.

This can place serious constraints on fast decision-making and timely rollout of new services aligned with market needs.<\/p><p>By modernizing systems through modernization, companies can build IT foundations that respond to change with exceptional flexibility. This not only greatly improves business process efficiency but also enables rapid launch of new services aligned with market trends. Even with limited human and physical resources, companies can focus on more strategic, higher-value work, ultimately strengthening their market competitiveness at fundamental level.<\/p><\/div><\/article><article class=\"smile-evidence-panel\"><div class=\"smile-evidence-panel__mark\"><span class=\"smile-evidence-panel__icon\" aria-hidden=\"true\"><svg class=\"smile-ui-icon smile-ui-icon--cost\" viewbox=\"0 0 64 64\" aria-hidden=\"true\" focusable=\"false\" stroke=\"currentColor\"><circle cx=\"32\" cy=\"32\" r=\"20\"\/><path d=\"M32 18v28\"\/><path d=\"M40 24c-2-4-14-5-16 1-3 8 17 5 14 14-2 6-14 5-17 0\"\/><\/svg><\/span><\/div><div class=\"smile-evidence-panel__body\"><h3 class=\"smile-evidence-panel__title\">Reduced Maintenance and Operating Costs<\/h3><p>As legacy systems age, they become increasingly prone to failures. As a result, companies must continue spending significant time and money on day-to-day operations and responses to unexpected issues. Even more serious is the difficulty of obtaining maintenance parts for old hardware or relying on software whose vendor support has already ended. These conditions make system maintenance more complex year by year and create hidden costs that put pressure on corporate finances.<\/p><p>By carrying out modernization and migrating systems to modern environments, companies can dramatically reduce maintenance and operations costs. In stable, up-to-date system environments, risk of unexpected failures is greatly reduced, and teams no longer need to constantly address aging infrastructure. As result, IT departments can free up resources previously spent on maintenance and operations, then focus on more strategic, higher-value work such as DX initiatives and adoption of new technologies.<\/p><\/div><\/article><article class=\"smile-evidence-panel\"><div class=\"smile-evidence-panel__mark\"><span class=\"smile-evidence-panel__icon\" aria-hidden=\"true\"><svg class=\"smile-ui-icon smile-ui-icon--quality\" viewbox=\"0 0 64 64\" aria-hidden=\"true\" focusable=\"false\" stroke=\"currentColor\"><path d=\"M16 34 28 46 50 18\"\/><path d=\"M14 14h28\"\/><path d=\"M14 24h18\"\/><path d=\"M14 50h36\"\/><\/svg><\/span><\/div><div class=\"smile-evidence-panel__body\"><h3 class=\"smile-evidence-panel__title\">Productivity and Quality<\/h3><p>Legacy systems operated for many years often become black boxes due to aging architecture and repeated feature additions. This invisible structure makes adding new features and performing daily maintenance extremely difficult, resulting in major increases in development and operating time and costs. Such conditions not only reduce overall system productivity but also directly lead to lower service quality.<\/p><p>By using modernization to visualize current systems and rebuild them into modern, unified architecture, companies can greatly improve efficiency across development (Dev) and operations (Ops). In addition, by adopting modern development and operations practices such as DevOps and SRE, they can automate testing and deployment, enable continuous integration (CI) and continuous delivery (CD), dramatically accelerate software release cycles, and significantly improve quality of services and products delivered. This becomes strong foundation for responding quickly to market changes and continuously providing innovative services.<\/p><\/div><\/article><article class=\"smile-evidence-panel\"><div class=\"smile-evidence-panel__mark\"><span class=\"smile-evidence-panel__icon\" aria-hidden=\"true\"><svg class=\"smile-ui-icon smile-ui-icon--performance\" viewbox=\"0 0 64 64\" aria-hidden=\"true\" focusable=\"false\" stroke=\"currentColor\"><path d=\"M12 46a22 22 0 1 1 40 0\"\/><path d=\"M32 32 44 20\"\/><path d=\"M20 46h24\"\/><path d=\"M18 34h4\"\/><path d=\"M42 34h4\"\/><\/svg><\/span><\/div><div class=\"smile-evidence-panel__body\"><h3 class=\"smile-evidence-panel__title\">Improved performance<\/h3><p>Stable system operation is critical for companies to provide services continuously and maintain customer trust. However, because legacy systems are aging and structurally complex, they always carry risk of unexpected system failures and performance degradation. In large-scale environments with complex system integrations in particular, major failures can stop services, and in worst cases, lead to serious security incidents such as personal data leaks, making them major concern for companies.<\/p><p>Improving overall system performance through modernization greatly reduces these risks. With latest technologies and optimized architecture, system operates more stably, and even if system failure occurs, downtime can be dramatically shortened. This minimizes impact on services and ensures business continuity.<\/p><p>In summary, modernization addresses complex challenges of aging systems, including lack of flexibility, high maintenance and operations costs, declining productivity and quality, and performance and security risks. Through this strategic approach, companies can improve adaptability, reduce operating costs, raise operational efficiency and service quality, and ultimately establish competitive advantage in market.<\/p><\/div><\/article><\/div><\/div><\/div>\n\n\n\n<div id=\"section-3\" class=\"wp-block-group smile-section\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\"><div class=\"smile-section__head\"><div class=\"smile-section__number\">03<\/div><h2 class=\"smile-section__title\">Modernization methods<\/h2><\/div>\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"739\" src=\"https:\/\/smilesoftware.org\/wp-content\/uploads\/2026\/06\/SmileSoftware-\u30e2\u30c0\u30ca\u30a4\u30bc\u30fc\u30b7\u30e7\u30f3\u306e\u624b\u6bb5-2.png\" alt=\"\u2018\u2019\u30ec\u30ac\u30b7\u30fc\u30b7\u30b9\u30c6\u30e0\u8131\u5374\u2018\u2019\u30e2\u30c0\u30ca\u30a4\u30bc\u30fc\u30b7\u30e7\u30f3\u3068\u306f\uff1f\u30e1\u30ea\u30c3\u30c8\u30845\u3064\u306e\u624b\u6bb5\u3084\u6210\u529f\u306e\u30dd\u30a4\u30f3\u30c8\u3092\u89e3\u8aac\" class=\"wp-image-4661\" srcset=\"https:\/\/smilesoftware.org\/wp-content\/uploads\/2026\/06\/SmileSoftware-\u30e2\u30c0\u30ca\u30a4\u30bc\u30fc\u30b7\u30e7\u30f3\u306e\u624b\u6bb5-2.png 1024w, https:\/\/smilesoftware.org\/wp-content\/uploads\/2026\/06\/SmileSoftware-\u30e2\u30c0\u30ca\u30a4\u30bc\u30fc\u30b7\u30e7\u30f3\u306e\u624b\u6bb5-2-300x217.png 300w, https:\/\/smilesoftware.org\/wp-content\/uploads\/2026\/06\/SmileSoftware-\u30e2\u30c0\u30ca\u30a4\u30bc\u30fc\u30b7\u30e7\u30f3\u306e\u624b\u6bb5-2-768x554.png 768w, https:\/\/smilesoftware.org\/wp-content\/uploads\/2026\/06\/SmileSoftware-\u30e2\u30c0\u30ca\u30a4\u30bc\u30fc\u30b7\u30e7\u30f3\u306e\u624b\u6bb5-2-18x12.png 18w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n<p>Modernization mainly includes following five methods.

Especially in large-scale systems or legacy code that has accumulated complex modifications over many years, unexpected dependencies and inefficient logic are often deeply hidden, so this work requires advanced technical expertise and extensive experience.<\/p><\/div><div class=\"smile-insight-card\"><div class=\"smile-insight-card__head\"><span class=\"smile-insight-card__icon\" aria-hidden=\"true\"><svg class=\"smile-ui-icon smile-ui-icon--refactor\" viewbox=\"0 0 64 64\" aria-hidden=\"true\" focusable=\"false\" stroke=\"currentColor\"><circle cx=\"21\" cy=\"20\" r=\"6\"\/><circle cx=\"43\" cy=\"44\" r=\"6\"\/><path d=\"M27 20h10c7 0 11 4 11 11v7\"\/><path d=\"m42 32 6 6 6-6\"\/><path d=\"M37 44H27c-7 0-11-4-11-11v-7\"\/><path d=\"m22 32-6-6-6 6\"\/><\/svg><\/span><h3 class=\"smile-insight-card__title\">Refactoring<\/h3><\/div><p>Refactoring is a method for reorganizing and optimizing the internal structure of software without changing any externally visible functions or behavior. Unlike rewriting, which changes the programming language or platform itself, refactoring keeps the current language and existing architecture while improving code readability, maintainability, and efficiency. This approach can significantly improve future development efficiency and incident response speed without compromising overall system performance. Especially in legacy systems that have undergone years of irregular modifications and feature additions, refactoring is a highly effective way to eliminate technical debt, maintain system health, and support long-term operation.<\/p><\/div><div class=\"smile-insight-card\"><div class=\"smile-insight-card__head\"><span class=\"smile-insight-card__icon\" aria-hidden=\"true\"><svg class=\"smile-ui-icon smile-ui-icon--document\" viewbox=\"0 0 64 64\" aria-hidden=\"true\" focusable=\"false\" stroke=\"currentColor\"><path d=\"M18 8h20l10 10v38H18z\"\/><path d=\"M38 8v12h10\"\/><path d=\"M24 32h18\"\/><path d=\"M24 42h18\"\/><path d=\"M24 22h8\"\/><\/svg><\/span><h3 class=\"smile-insight-card__title\">Redocumentation<\/h3><\/div><p>Redocumentation is the process of recreating and updating missing documentation, or documents such as specifications and design materials that have become outdated and no longer reflect the current state of an existing legacy system. In systems that have been operated for many years, internal structures and processing logic are often black boxes. Redocumentation helps visualize the entire system and deepen shared understanding among stakeholders. This improves maintenance and operations efficiency and quality, while also providing highly reliable information for decisions on future modernization strategies such as refactoring and rebuilding. Redocumentation plays an important role as a preparatory stage before more advanced modernization methods and builds a strong foundation for the success of the overall modernization strategy.<\/p><\/div><\/div><\/div><\/div>\n\n\n\n<div id=\"section-4\" class=\"wp-block-group smile-section\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\"><div class=\"smile-section__head\"><div class=\"smile-section__number\">04<\/div><h2 class=\"smile-section__title\">Key points for successful modernization<\/h2><\/div>\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1536\" height=\"1024\" src=\"https:\/\/smilesoftware.org\/wp-content\/uploads\/2026\/06\/redmine-1299-image2.png\" alt=\"\u2018\u2019\u30ec\u30ac\u30b7\u30fc\u30b7\u30b9\u30c6\u30e0\u8131\u5374\u2018\u2019\u30e2\u30c0\u30ca\u30a4\u30bc\u30fc\u30b7\u30e7\u30f3\u3068\u306f\uff1f\u30e1\u30ea\u30c3\u30c8\u30845\u3064\u306e\u624b\u6bb5\u3084\u6210\u529f\u306e\u30dd\u30a4\u30f3\u30c8\u3092\u89e3\u8aac\" class=\"wp-image-4523\" srcset=\"https:\/\/smilesoftware.org\/wp-content\/uploads\/2026\/06\/redmine-1299-image2.png 1536w, https:\/\/smilesoftware.org\/wp-content\/uploads\/2026\/06\/redmine-1299-image2-300x200.png 300w, https:\/\/smilesoftware.org\/wp-content\/uploads\/2026\/06\/redmine-1299-image2-1024x683.png 1024w, https:\/\/smilesoftware.org\/wp-content\/uploads\/2026\/06\/redmine-1299-image2-768x512.png 768w, https:\/\/smilesoftware.org\/wp-content\/uploads\/2026\/06\/redmine-1299-image2-18x12.png 18w, https:\/\/smilesoftware.org\/wp-content\/uploads\/2026\/06\/redmine-1299-image2-930x620.png 930w\" sizes=\"auto, (max-width: 1536px) 100vw, 1536px\" \/><\/figure>\n\n\n<p>Modernization is more than system renewal; it is highly strategic initiative that strengthens corporate competitiveness and drives DX (digital transformation). To make modernization successful, companies must address following three key points thoroughly from both strategic and practical perspectives.<\/p><div class=\"smile-insight-cards\"><div class=\"smile-insight-card\"><div class=\"smile-insight-card__head\"><span class=\"smile-insight-card__icon\" aria-hidden=\"true\"><svg class=\"smile-ui-icon smile-ui-icon--policy\" viewbox=\"0 0 64 64\" aria-hidden=\"true\" focusable=\"false\" stroke=\"currentColor\"><path d=\"M18 8h20l10 10v38H18z\"\/><path d=\"M38 8v12h10\"\/><path d=\"M24 32h18\"\/><path d=\"M24 42h14\"\/><path d=\"m24 22 4 4 8-8\"\/><\/svg><\/span><h3 class=\"smile-insight-card__title\">Risk Assessment and Countermeasures<\/h3><\/div><p>Modernization accelerates corporate DX, but also carries potential risks such as data corruption, business interruption, and impact on existing application operations. Complex structures of legacy systems in particular can cause unexpected issues. Before project starts, it is essential to accurately identify impact across entire system and thoroughly assess all risks. By preparing countermeasures in advance, companies can smooth migration process, minimize business impact, and greatly increase likelihood of successful modernization.<\/p><\/div><div class=\"smile-insight-card\"><div class=\"smile-insight-card__head\"><span class=\"smile-insight-card__icon\" aria-hidden=\"true\"><svg class=\"smile-ui-icon smile-ui-icon--operations\" viewbox=\"0 0 64 64\" aria-hidden=\"true\" focusable=\"false\" stroke=\"currentColor\"><circle cx=\"32\" cy=\"32\" r=\"9\"\/><path d=\"M32 8v8\"\/><path d=\"M32 48v8\"\/><path d=\"m15 15 6 6\"\/><path d=\"m43 43 6 6\"\/><path d=\"M8 32h8\"\/><path d=\"M48 32h8\"\/><path d=\"m15 49 6-6\"\/><path d=\"m43 21 6-6\"\/><\/svg><\/span><h3 class=\"smile-insight-card__title\">Ensuring Communication<\/h3><\/div><p>Because modernization affects entire system and, ultimately, business processes across company, smooth cross-department communication is critical to success.

Rather than merely \u201creplacing\u201d systems, it aims to dramatically improve productivity, flexibility, security, and performance across the entire system while making full use of the business assets and know-how that companies have built over many years. Ultimately, it can be viewed as a comprehensive transformation process that accelerates DX and strengthens competitiveness.<\/p><\/div><\/article><article class=\"smile-evidence-panel\"><div class=\"smile-evidence-panel__mark\"><span class=\"smile-evidence-panel__icon\" aria-hidden=\"true\"><svg class=\"smile-ui-icon smile-ui-icon--compare\" viewbox=\"0 0 64 64\" aria-hidden=\"true\" focusable=\"false\" stroke=\"currentColor\"><path d=\"M14 22h28\"\/><path d=\"m34 14 8 8-8 8\"\/><path d=\"M50 42H22\"\/><path d=\"m30 34-8 8 8 8\"\/><\/svg><\/span><\/div><div class=\"smile-evidence-panel__body\"><h3 class=\"smile-evidence-panel__title\">Q2: What is difference between modernization and legacy migration?<\/h3><p>Modernization and migration are both approaches for moving away from legacy systems, but they differ clearly in purpose and scope of change. Migration focuses on moving old systems and data to a new environment while largely keeping existing functions and structure unchanged. Modernization, by contrast, uses existing assets while also changing system architecture, code, business processes, and other elements to strengthen and optimize system itself in line with current technologies and business needs. In short, migration is closer to \u201cmoving,\u201d while modernization aims to \u201cmodernize and evolve.\u201d<\/p><\/div><\/article><article class=\"smile-evidence-panel\"><div class=\"smile-evidence-panel__mark\"><span class=\"smile-evidence-panel__icon\" aria-hidden=\"true\"><svg class=\"smile-ui-icon smile-ui-icon--benefit\" viewbox=\"0 0 64 64\" aria-hidden=\"true\" focusable=\"false\" stroke=\"currentColor\"><path d=\"M12 50h40\"\/><path d=\"M18 42V30\"\/><path d=\"M30 42V22\"\/><path d=\"M42 42V14\"\/><path d=\"m38 18 4-4 4 4\"\/><\/svg><\/span><\/div><div class=\"smile-evidence-panel__body\"><h3 class=\"smile-evidence-panel__title\">Q3: What are benefits of modernization?<\/h3><p>By advancing modernization, companies can resolve wide range of challenges posed by legacy systems and gain key benefits. Specifically, they can build an IT foundation that responds flexibly to changes in business environment and sharply reduce maintenance and operation costs caused by aging systems. They can also achieve major gains in productivity and service quality, strengthen overall system performance and security levels, and ensure business continuity. These benefits ultimately strengthen market competitiveness at fundamental level and accelerate DX.<\/p><\/div><\/article><article class=\"smile-evidence-panel\"><div class=\"smile-evidence-panel__mark\"><span class=\"smile-evidence-panel__icon\" aria-hidden=\"true\"><svg class=\"smile-ui-icon smile-ui-icon--methods\" viewbox=\"0 0 64 64\" aria-hidden=\"true\" focusable=\"false\" stroke=\"currentColor\"><circle cx=\"16\" cy=\"32\" r=\"5\"\/><circle cx=\"48\" cy=\"18\" r=\"5\"\/><circle cx=\"48\" cy=\"46\" r=\"5\"\/><path d=\"M21 32h10\"\/><path d=\"M31 32 43 20\"\/><path d=\"M31 32 43 44\"\/><\/svg><\/span><\/div><div class=\"smile-evidence-panel__body\"><h3 class=\"smile-evidence-panel__title\">Q4: What approaches are used for modernization?<\/h3><p>Modernization mainly involves five methods. Replacement rebuilds system from scratch for complete renewal. Rehosting moves system to new hardware environment without changing program. Rewriting converts source code to a new language without changing functionality. Refactoring optimizes internal structure without changing external functions. Redocumentation reorganizes existing documentation. Choosing best method based on current state and goals of legacy system is essential.<\/p><\/div><\/article><article class=\"smile-evidence-panel\"><div class=\"smile-evidence-panel__mark\"><span class=\"smile-evidence-panel__icon\" aria-hidden=\"true\"><svg class=\"smile-ui-icon smile-ui-icon--roadmap\" viewbox=\"0 0 64 64\" aria-hidden=\"true\" focusable=\"false\" stroke=\"currentColor\"><path d=\"M16 52V12\"\/><path d=\"M16 14h24l-4 8 4 8H16\"\/><path d=\"M22 52c7-10 15-10 24 0\"\/><\/svg><\/span><\/div><div class=\"smile-evidence-panel__body\"><h3 class=\"smile-evidence-panel__title\">Q5: Where should modernization begin?<\/h3><p>First step in considering modernization is to accurately understand current state of existing legacy system and clearly define what you want to achieve.
