# Resize an instance via the OVHcloud Control Panel

## Objective

If your instance lacks resources due to increased activity or new needs, you can increase its resources in just a few clicks with the Public Cloud.

**This guide explains how to resize your instance from the OVHcloud Control Panel.**

:::warning
Only upscaling is possible for classic models.
In addition, this manipulation causes the instance to be shut down for the time of the operation.

:::

:::tip
Flex instances allow resizing to higher or lower models due to a locked single disk size.

:::

## Requirements

- A [Public Cloud instance](https://www.ovhcloud.com/en-gb/public-cloud/) in your OVHcloud account


***

### OVHcloud Control Panel Access

- **Direct link:** <ManagerLink to="/#/pci/projects">Public Cloud Projects</ManagerLink>
- **Navigation path:** <code className="action">Public Cloud</code> > Select your project

***


## Instructions

Click on `Instances
` in the left-hand menu.
Click on `...
` to the right of the instance, and select `Edit
`. You can also access this action from the instance details by clicking on its name, then on `Modify model
`.
In the new tab, scroll down to the **Template** section to select the model of your choice.

:::info
For classic models, you can switch to any flavor that has a similar or bigger disk. You can't switch to a model with a smaller disk.

Only **Flexible instances** can be upgraded and downgraded while maintaining a fixed disk size of 50GB.

:::

If your disk is equal to or smaller than 50GB, you can switch to a `Flexible instance
` if desired.
:::warning
If you are editing a flex instance, you cannot revert to a classic instance via the Control Panel. For more information, consult the guide on [Revert a flex instance](/en/guides/public-cloud/compute/revert-a-flex-instance.md).

:::

Once the selection has been made, click on `Modify template
` to confirm your choice.
### Resizing a disk in Windows

When performing a resize for a Windows Instance, the partition size is not automatically updated. You must extend it using the **disk manager**:

- Right-click on the <code className="action">Start</code> menu and launch the disk manager by clicking on <code className="action">Disk Management</code>:

- Right-click on the main partition, then click on <code className="action">Extend Volume</code>.

- In the `Extend Volume Wizard` menu, click on <code className="action">Next</code> to proceed. In the next tab, choose the disk resources to extend and click on <code className="action">Next</code>.
