Migrating legacy systems to modern Java environments is a critical undertaking for organizations seeking improved performance, maintainability, and scalability. Legacy systems, often developed in outdated programming languages, pose significant challenges due to their monolithic architectures, lack of documentation, and compatibility issues. This manuscript explores various migration strategies, including rehosting, replatforming, refactoring, and rearchitecting, to transition legacy applications to modern Java-based frameworks such as Spring Boot, Quarkus, and Jakarta EE. A thorough literature review identifies best practices and case studies, while the proposed methodology outlines a structured approach to migration. The results demonstrate the effectiveness of Java-based modernization in enhancing system performance, security, and maintainability. The study concludes by emphasizing the importance of proper planning, automated tools, and iterative migration to mitigate risks and ensure a smooth transition.
