Migrating Between Monoliths and Microservices with AI Agents

AI Agents Can Migrate Your Architecture — But Only If They Understand It First The microservices vs. monolith debate has been raging for over a decade. But here's the thing — in 2026, the conversation has shifted. It's no longer about which architecture is "better." It's about when to migrate between them and, more importantly, how to do it safely . With AI coding agents becoming genuinely capable — Claude Code, Cursor, Copilot Workspace — the "how" is getting easier. Agents can refactor modules, split services, merge repositories, and rewrite API boundaries. But there's a critical step that most teams skip, and it's the reason migrations still fail: understanding the existing system first. Before any agent writes a single line of migration code, two people need to deeply understand the current architecture: the architect making the decision, and the agent executing it.
