In the ever-evolving world of software development, one of the most significant challenges developers face is ensuring that their code is portable across different platforms and environments. With the rise of diverse operating systems, hardware architectures, and cloud infrastructure, code portability has become a critical concern for developers seeking to deploy their applications seamlessly across various environments. To address this challenge, a new innovative tool has emerged: the Portability Analyzer New.

Before making structural code changes, the tool evaluates your system components. It categorizes components into three distinct buckets:
