Amazon EC2 - Convert EBS root device with instance store root device

Question

I see that you can convert an instance stored instance to be EBS backed as this question shows. However, I want to do the opposite, take an EBS backed instance and convert

Answer 1

1. Launch an instance-store instance from an AMI that uses the same kernel used by your EBS-backed AMI.

2. Create an EBS volume from the snapshot underlying the EBS AMI. (Alternatively, launch an instance of the EBS AMI and Stop the instance when it begins booting. Detach the root volume from the instance - this is usually the volume attached to /dev/sda1.)

3. Attach the EBS volume to the instance-store instance.

4. rsync the contents of the EBS volume to the root volume.

5. Create an instance-store AMI using the standard methods.

6. Detach the EBS volume and delete it. If you launched an EBS instance in step 2, terminate it.
