This guide walks you through the process of migrating a Svelte or Svelte Kit app from version 4 to Svelte 5. The major changes include a ground-up rewrite for better performance, new syntax for reactivity using 'runes', and native TypeScript support in templates. The guide also covers how to use the new Svelte CLI for migrations and updates. Each step is illustrated with practical examples, including converting state management from stores to runes, and an overview of the backward compatibility and incremental upgrading process.
