How to convert CENTOS5 PV AMI to HVM one?

Question

I asked to migrate existing CENTOS5-basedEC2 server to the new T2 instance. I created AMI, but it can't be launched as T2 instance because T2 supports only HVM virtualization. There are few manuals for converting AMI from PV to HVM (http://www.nixhat.com/2014/01/migrate-aws-pv-to-hvm-instance/, for example); but in order to do it, I need "to implant" HVM kernel into my server. But there is no CENTOS5 HVM AMIs! Is there any workaround?

May I use just vanilla CENTOS5 kernel - AFAIK, PV uses modified kernel, not sure about HVM?

TIA, Vitaly

How about saving the volume of your EC2 instance, implanting that volume on the new instance and setting grub to boot from the newly attached volume? — Lars, Jul 16 '14 at 16:34
I don't think this is supported in CentOS 5. You can do it in CentOS 6, though. And it's past time to upgrade anyway. — Michael Hampton, Jul 16 '14 at 17:01
@Lars - it exactly that I want to do, but I need HVM CentOS5 image for this... — Vitaly Karasik DevOps, Jul 17 '14 at 04:27
This worked for me on Fedora PV to HVM. http://serverfault.com/a/617371/182827 — Anshu Prateek, Aug 09 '14 at 08:56

I found CentOS 5 HVM AMI in one of AWS regions and converted my image using method similar to http://www.nixhat.com/2014/01/migrate-aws-pv-to-hvm-instance, i.e. by cloning my "/" to HVM AMI.
