Migrating IBM Semeru Runtime Certified Edition for z/OS Version 25 to compile with IBM Open XL C/C++ 2.2 is a meaningful effort that extends beyond a simple compiler replacement. It requires careful consideration of build systems and platform-specific behaviours, while also providing an opportunity to improve code quality. This post shares our experience migrating the Java 25 build on z/OS from XL C/C++ to Open XL C/C++, highlighting key challenges, lessons learned, and practical insights for teams considering a similar transition.
