IBM Bob is an AI-powered software development lifecycle partner that automates Java application modernization. The post walks through converting a legacy WebSphere application to OpenLiberty in two phases: replatforming and Java runtime upgrade. Bob combines deterministic rule-based changes (via IBM Application Modernization Accelerator) with autonomous AI agents that iteratively analyze code, propose fixes, run unit tests and Maven builds, validate the running application, and update a todo list based on errors encountered. Developers retain oversight by reviewing and approving changes, while Bob handles complex refactoring tasks that previously required extensive manual effort.
