I have created an instance running ubuntu os. Now I need to change the OS from ubuntu to cent OS. For that I need set the "deleteOn Termination" flag as false to attach it to the new instance.
I used the following command but it tells -> "Only one instance ID may be specified. (-h for usage)"
ec2-modify-instance-attribute --region device=vol-id:false
I am struck with this few hours. Can any one answer for this; How to resolve this issue?
Thanks for the reply in advance
