# How Wix Saved 650 Developer-Days in One Quarter by Automating Code Migrations

**[Wix Engineering](https://daily.dev/sources/wix_eng)** · 8 min read · 1 upvotes · 0 comments

## Summary

Wix built an internal Code Migration Platform to automate cross-team code migrations at scale — 50 migrations per year touching 6,000 repositories. The platform uses a three-layer architecture: a migration dashboard for target discovery, an execution layer running AI code agents on Buildkite to open repos and create PRs automatically, and a database layer for tracking. A Prompt Bank stores versioned migration logic that improves over time based on manual adjustments made by service owners. Key merge-rate improvements came from clear ownership, rich PR context, and automerge for safe changes. Results: 650 developer-days saved in one quarter, with 88% of PRs merged without manual changes. Future plans include conversational migration via MCP and automatic build failure fixes.
