Google Cuts Code Migration Time in Half with AI
2025-01-16
Google reports using its AI tools to halve the time required for code migrations. This involved projects like migrating 32-bit IDs to 64-bit IDs in the Google Ads codebase, upgrading JUnit testing libraries, and replacing the Joda time library. While human review is still necessary, the AI significantly sped up the process, reducing what would have taken hundreds of engineering years to just months. Google emphasizes the AI should be used in conjunction with traditional methods for optimal efficiency and cost management.
