It delegates to the [`svelte-migrate`](https://www.npmjs.com/package/svelte-migrate) package. Some migrations may annotate your codebase with tasks for completion that you can find by searching for `@migration`. ## Usage ```sh npx sv migrate ``` You can also specify a migration directly via the CLI: ```sh npx sv migrate [migration] ``` ## Migrations ### `app-state` Migrates `$app/stores` usage to `$app/state` in `.svelte` files. See the [migration guide](/docs/kit/migrating-to-sveltekit-2#SvelteKit-2.12:-$app-stores-deprecated) for more details. ### `svelte-5` Upgrades a Svelte 4 app to use Svelte 5, and updates individual components to use [runes](../svelte/what-are-runes) and other Svelte 5 syntax ([see migration guide](../svelte/v5-migration-guide)). ### `self-closing-tags` Replaces all the self-closing non-void elements in your `.svelte` files.
