# `@vercel/next` Legacy Routes Optimized Lambdas Opt-out
|
|
|
|
#### Why This Warning Occurred
|
|
|
|
`@vercel/next` by default now bundles pages into optimized functions, minimizing bootup time and increasing overall application throughput.
|
|
When legacy `routes` are added in `now.json` or `vercel.json`, they cause conflicts with this optimization, so it is opted-out.
|
|
|
|
#### Possible Ways to Fix It
|
|
|
|
Migrate from using legacy `routes` to the new `rewrites`, `redirects`, and `headers` configurations in your `now.json` or `vercel.json` file or leverage them directly in your `next.config.js` with the built-in [custom routes support](https://github.com/vercel/next.js/issues/9081)
