Once I have created an EBS of IOPS type and attached to an EC2 volume, is there a way to change its settings such as storage and IOPS? I am fine detaching it and making changes. Obviously I want to retain data.

I am looking for an answer preferably on the AWS Console but even a command line approach is welcome.

I am using Windows AMI.
