Scaling the adoption of Kotlin within an organization involves strategic decision-making and careful planning, especially when transitioning from a Java-dominated environment. Urs Peter, a seasoned software engineer and Kotlin trainer, outlines various strategies for integrating Kotlin, emphasizing the importance of aligning migration efforts with organizational goals. For end-of-life applications, maintaining the status quo is recommended, while new systems should default to Kotlin. Active applications require a pragmatic, feature-driven approach to migration, combining new feature development with conversion efforts to add tangible business value. Java-to-Kotlin conversion can be approached through complete rewrites, IDE auto-conversion with manual refinements, AI-assisted conversion, or auto-conversion at scale, each with its own set of challenges and prerequisites. Successful large-scale adoption is not just about converting code but also about building team expertise, establishing coding standards, and creating sustainable processes. While Kotlin offers a modern, efficient, and developer-friendly alternative to Java, organizations must assess their readiness to embrace this change and invest in the necessary training and infrastructure.
