# Edit Instance

When you need to modify the "Volume Disk Size", "Expose HTTP Ports" or "Expose TCP Ports" of a GPU instance, you can use [Novita AI](https://novita.ai) **Edit Instance** feature. Here's how to use this feature.

1. Go to the [Instances](https://novita.ai/gpus-console/instances) page and locate the instance you want to modify. Click "More Operations - Edit".

2. In the pop-up edit window, modify the instance configuration and click the "Save" button.

> [!TIP]
>
> * You can modify the instance configuration while the instance is running, and the instance will not restart after modification;
> * Changes are expected to take effect within 1 minute.

> [!WARNING]
>
> * The "Volume Disk Size" configuration can only be increased, not decreased;
> * New "Expose HTTP Ports" and "Expose TCP Ports" cannot conflict with ports that are already in use.
