Answer 1

This is the aws suggested solution You can detach the root volume from the original instance after stopping it. The root volume is attached at /dev/sda1. Once this is detached, please attach it to the new instance. After the volume is attached, you may have to mount it from the OS. After it's mounted, you should see the data within it.

After you've done adding the new key, you can detach it and attach to the original instance at /dev/sda1.

I suggest creating a snapshot of the root volume before making any changes.

Before trying out any solutions just try out in the not important instances or spot instances
