# Starwind UI V3 Migration

Starwind Pro's current registry targets Starwind UI v3. Migrate an older Astro project before you
install or update current Pro blocks.

```bash
pnpm dlx starwind@latest migrate
```

The guided migration can back up existing Starwind component folders, replace registered V2
components, preserve unrelated custom folders, install Runtime packages, and write the current
`starwind.config.json` format.

See the full [Starwind UI migration guide](https://starwind.dev/docs/getting-started/migration/)
for every step, option, and troubleshooting tips!

## Frozen V2 registry

The frozen V2 registry is an escape hatch for projects that must remain on Starwind UI v2. It is
the last Pro source verified for UI major 2 for those staying on Starwind V2. For new and updated blocks, follow the V3 migration guide and install from the current Pro registry.
