With the rapid development of AI tools, the IT industry has reached a point where building a new project is often cheaper and easier than maintaining an existing one. However, for many large, long-running projects, rewriting everything from scratch is not the best option — especially if teams learn how to maintain and evolve them with the help of agentic tools. In this talk, we will explore real-world experience working with such projects, covering key aspects of collaboration with people, tools, technologies, and processes through practical case studies.

I will talk about the problems and nuances of migration from legacy products. Also, using my own experience, I will share how we worked with legacy in our team, what challenges and problems we faced, and how we got out of these situations during migration.
