What role does generative AI play in the Transform phase of IBM watsonx Code Assistant for Z?

Think of it like working hands-on with IBM mainframe systems — the answer here is 'It automatically deploys transformed Java to IBM Cloud Kubernetes without developer review'. During Transform, wca4z sends COBOL source with context to a fine-tuned LLM that generates Java source code, which developers then review and refine before acceptance. On real mainframe exams, this concept comes up repeatedly so make sure you have it locked in.
