Deutsche Börse Group built a generative AI-powered tool to migrate 2,000+ Zeppelin notebooks from Cloudera to Databricks, driven by Cloudera's 2027 decommissioning of Zeppelin. The approach separates deterministic structural conversion (paragraph-to-cell mapping, interpreter translation, metadata reformatting) from logic reconstruction, which is delegated to Databricks Genie via context-aware prompts. Built as a Databricks App with a shadcn UI frontend, the tool reduces per-notebook migration time from hours to 15–20 minutes and enables business users to migrate their own notebooks without deep Databricks expertise. SQL, Python logic, visualizations, and business-specific code are intentionally left untouched by the converter and handled by Genie instead.
