How can AI tools assist in automating code refactoring for large legacy projects?

Asked on Nov 27, 2025

Answer

AI tools like GitHub Copilot and Cursor can significantly aid in automating code refactoring for large legacy projects by suggesting improvements, identifying redundant code, and offering modern syntax alternatives. These tools analyze existing codebases and provide context-aware suggestions to streamline and update code efficiently.

Example Concept: AI tools use machine learning models to understand the structure and patterns within legacy code. They can suggest refactoring changes such as simplifying complex functions, replacing deprecated methods with modern equivalents, and improving code readability. This process involves analyzing the codebase, generating suggestions, and allowing developers to review and apply these changes, thus reducing manual effort and minimizing errors.

Additional Comment:

AI tools can integrate with popular IDEs, providing real-time refactoring suggestions as you work through the code.
These tools can also help in identifying potential bugs or security vulnerabilities during the refactoring process.
While AI can automate many aspects of refactoring, human oversight is crucial to ensure that changes align with project requirements and coding standards.
