# 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 <a href="https://novita.ai">Novita AI</a> **Edit Instance** feature. Here's how to use this feature.

1. Go to the <a href="https://novita.ai/gpus-console/instances">Instances</a> 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.
</Tip>

<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.
</Warning>
