 ### Setting the Node version
 
-# [Windows](#tab/windows-setting-the-node-version)
+The way that you upgrade your Node.js version depends on the OS on which your function app runs.
 
-For Windows function apps, target the version in Azure by setting the `WEBSITE_NODE_DEFAULT_VERSION` [app setting](functions-how-to-use-azure-function-app-settings.md#settings) to a supported LTS version, such as `~18`.
+# [Windows](#tab/windows)
 
-# [Linux](#tab/linux-setting-the-node-version)
+When running on Windows, the Node.js version is set by the [`WEBSITE_NODE_DEFAULT_VERSION`](./functions-app-settings.md#website_node_default_version) application setting. This setting can be updated either by using the Azure CLI or in the Azure portal.
 
-For Linux function apps, run the following Azure CLI command to update the Node version.
+# [Linux](#tab/linux)
 
-```azurecli
-az functionapp config set --linux-fx-version "node|18" --name "<MY_APP_NAME>" --resource-group "<MY_RESOURCE_GROUP_NAME>"
+When running on Windows, the Node.js version is set by the [linuxfxversion](./functions-app-settings.md#linuxfxversion) site setting. This setting can be updated using the Azure CLI.
+

+
+For more information about Node.js versions, see [Supported versions](#supported-versions).
+
+Before upgrading your Node.js version, make sure your function app is running on the latest version of the Azure Functions runtime. If you need to upgrade your runtime version, see [Migrate apps from Azure Functions version 3.x to version 4.x](migrate-version-3-version-4.md?pivots=programming-language-javascript).  
+
+# [Azure CLI](#tab/azure-cli/windows)
+
+Run the Azure CLI [`az functionapp config appsettings set`](/cli/azure/functionapp/config#az-functionapp-config-appsettings-set) command to update the Node.js version for your function app running on Windows:
+
+```azurecli-interactive
+az functionapp config appsettings set  --settings WEBSITE_NODE_DEFAULT_VERSION=~18 \
+ --name <FUNCTION_APP_NAME> --resource-group <RESOURCE_GROUP_NAME> 
+```
+
+This sets the [`WEBSITE_NODE_DEFAULT_VERSION` application setting](./functions-app-settings.md#website_node_default_version) the supported LTS version of `~18`.
+
+# [Azure portal](#tab/azure-portal/windows)
+
+Use the following steps to change the Node.js version:
+
+[!INCLUDE [functions-set-nodejs-version-portal](../../includes/functions-set-nodejs-version-portal.md)]
+
+# [Azure CLI](#tab/azure-cli/linux)
+
+Run the Azure CLI [`az functionapp config set`](/cli/azure/functionapp/config#az-functionapp-config-set) command to update the Node.js version for your function app running on Linux:
+
+```azurecli-interactive
+az functionapp config set --linux-fx-version "node|18" --name "<FUNCTION_APP_NAME>" \
+ --resource-group "<RESOURCE_GROUP_NAME>"
 ```
 
+This sets the base image of the Linux function app to Node.js version 18.
+
+# [Azure portal](#tab/azure-portal/linux)
+
+>[!NOTE]  
+> You can't change the Node.js version in the Azure portal when your function app is running on Linux in a Consumption plan. Instead use the Azure CLI.
+
+For Premium and Dedicated plans, use the following steps to change the Node.js version:  
+
+[!INCLUDE [functions-set-nodejs-version-portal](../../includes/functions-set-nodejs-version-portal.md)]

-To learn more about Azure Functions runtime support policy, refer to this [article](./language-support-policy.md).
+After changes are made, your function app restarts. To learn more about Functions support for Node.js, see [Language runtime support policy](./language-support-policy.md).
