 In this guide, you will create a new [Next.js](https://nextjs.org/) application and deploy to Cloudflare Workers (with the new [<InlineBadge preset="beta" /> Workers Assets](/workers/static-assets/)) using the [`@opennextjs/cloudflare`](https://opennext.js.org/cloudflare) package.
 
 :::note
-If your Next.js app currently runs on Vercel, you can easily migrate your Next.js app to Cloudflare by using [Diverce](https://github.com/ygwyg/diverce), which will automatically add OpenNext to your project and create a pull request that makes it deployable to Cloudflare.
