In this session, Sandra Ahlgrimm will discuss the practical aspects of modernizing Java applications using various tools and techniques. The presentation will explore different strategies, emphasizing the importance of evaluating the current system to determine the best modernization approach. Key topics will include the "7 Rs" framework—rehosting, replatforming, refactoring, rearchitecting, rebuilding, replacing, and retiring outdated systems. Due to time constraints, the session will focus on refactoring and rearchitecting. Attendees will learn that while there is no single magical tool for migration, a combination of tools and methods can significantly streamline the modernization process, traditionally a time-consuming endeavor. Tools range from traditional tools like OpenRewrite to AI-driven methods. And aim to bring 6 months updating circles to days or weeks.

I'll start from an old Java 8 samples, available here: https://github.com/Azure-Samples/ms-identity-msal-java-samples

Discuss the theory of updating, including the 7 R principle.

Then Update in action using the OpenRewrite and AI driven Java Updater Microsoft created, discuss it's value, potential failures and opportunities.

It's a demo driven presentation using Java examples.
