NOTE: If you want to increase available disk space by adding a new EBS volume to your instance, refer to this guide instead.

The procedure consists of creating a new server using the same disk as the server to be modified, and then deleting the old one following the steps below.

  • Browse to the AWS Cloud Console. Log in if needed.

  • If required, use the region selector in the top right corner to switch to the region where your instance was launched.

  • In the left navigation bar, select the “Instances -> Instances” menu item.
