Modernize Software and Tackle Tech Debt at Big Bank Scale

Morgan Stanley's Dov Katz on saving tens of thousands of development hours with a single migration, across billions of lines of code. On-demand from Code Remix Summit 2025.

When you have billions of lines of code and thousands of repositories, maintenance and modernization get hard in ways smaller estates never see.

Dov Katz covers how Morgan Stanley is saving tens of thousands of development hours on a single migration using OpenRewrite recipes and Moderne, and what that unlocked for feature delivery, security compliance, and a more sustainable development lifecycle. He walks through the strategic planning that preceded the tooling, the implementation process across thousands of repositories, the real-world challenges met along the way, and practical strategies for reducing tech debt at scale.
