Yes. It does also contain the migration prompt, but also information on migrating yourself. Haven't used it myself, so YMMV: https://viteplus.dev/guide/migrate

We initially considered a paid license for companies when we announced Vite+. We decided that Vite+ can only achieve our mission of making JavaScript developers more productive than ever before when it is truly free and open source. We got tired of debating which features should be paid and how they should be gated, as this only creates friction in the workflows our open-source users already enjoy and love. Feedback from the community helped us reinforce our conviction. Therefore, we decided to fully open source Vite+ under the MIT license.
