How to migrate with Claude Code and not die trying
The author describes how using Claude Code significantly reduced the time and effort required for technical migrations, such as updating a website's design and transitioning tooling in a monorepo. Tasks that previously took weeks and were prone to procrastination were completed in days with the help of AI automation. The article highlights specific migrations to oxlint, oxfmt, and tsgo, emphasizing improvements in performance and developer efficiency.
- ▪The migration of the site's entire design, which previously would have taken two weeks, was completed in a couple of days using Claude Code.
- ▪Migrating from Biome to oxlint and oxfmt in a monorepo with 1,670 TypeScript files resulted in linting time dropping from 3.70 seconds to 0.49 seconds.
- ▪The switch to tsgo, a Go-based TypeScript compiler, aimed to leverage promised 7x to 10x performance improvements over the traditional TypeScript compiler.
- ▪Claude Code excels in migration tasks involving high-volume mechanical changes, clear automated feedback loops, and accessible documentation.
- ▪The author identifies toolchain migrations in large codebases as ideal use cases for AI agents due to their repetitive and rule-based nature.

Before Claude Code, that same migration would have eaten up two weeks of my time, and I'd probably have put it off for six months out of pure laziness. I've been doing migrations for years.
