-This article provides a guide to upgrade your existing Durable Functions app to newly-released version 4 of the Node.js programming model for Azure Functions from the existing version 3. If you are instead interested in creating a brand new v4 app, follow the Visual Studio Code quickstarts for [JavaScript](./quickstart-js-vscode.md?pivots=nodejs-model-v4) and [TypeScript](./quickstart-ts-vscode.md?pivots=nodejs-model-v4). This article uses "TIP" sections to highlight the most important concrete actions you should take to upgrade your app. Before following this guide, make sure you follow the general [version 4 upgrade guide](../functions-node-upgrade-v4.md). You can also learn more about the new v4 programming model through the [Node.js developer reference](../functions-reference-node.md?pivots=nodejs-model-v4).

+>[!TIP]
+> Remove `function.json` files from your Durable Functions app. Instead, register your durable functions using the methods on the `app` namespace: `df.app.orchestration()`, `df.app.entity()`, and `df.app.activity()`.
+
+
+## Update your Durable Client input config
+
+In the v4 model, registering extra inputs has been moved from `function.json` files to your own code! You can use the `input.durableClient()` method to register an extra durable client input to your preferred durable client function. You can then use `getClient()` to retrieve the client instance as before. See the example below using an HTTP trigger.
