#Migration

AI Agent for Code Migrations

Framework upgrades and API migrations — handled overnight.

The Problem

Migrations are the tasks everyone dreads. Upgrading a framework version, switching from one library to another, or updating to a new API means touching hundreds of files with repetitive changes. It's boring, error-prone, and blocks feature development for days or weeks.

The Solution

Zowl turns migrations into an overnight operation. Define the source and target patterns, and AI agents apply the changes file-by-file with full context. Each migration is tested independently, and only passing changes become PRs. What used to take a sprint happens in one night.

How It Works

Define migration rules: what pattern to find, what to replace, which files to target.

Zowl scans your codebase and generates a task list of files needing migration.

AI agents migrate each file independently with full project context.

Test suite and type checker run after each file migration.

Successful migrations become individual PRs for easy review.

Benefits

File-by-File Safety

Each file is migrated and tested independently. One failure doesn't block the rest.

Context-Aware Changes

Agents understand your codebase — they don't just find-and-replace, they adapt to each file's patterns.

Multi-Night Migrations

Large migrations can run across multiple nights. Zowl tracks progress and picks up where it left off.

Zero Sprint Disruption

Migrations happen overnight. Your team keeps shipping features during the day.

Example Pipeline: React 18 to 19 Migration

1.Scan for deprecated React 18 patterns
2.Agent migrates each component to React 19 APIs
3.TypeScript compiler verifies type safety
4.Jest runs component tests
5.Opens PR per migrated file

Frequently Asked Questions

Framework upgrades (React, Next.js, Angular), library swaps (Moment to Day.js), API changes (REST to GraphQL), pattern migrations (classes to hooks), and module system changes (CommonJS to ESM).

Yes. Agents read changelogs and migration guides when provided. They adapt code to new APIs rather than doing blind replacements.

Failed migrations are logged and skipped. Successful ones proceed to PR. You can fix the remaining files manually or run another pipeline pass.
