EC2 Downgrade m1 small to t2 micro

Question

I am trying to downgrade our m1.small instance to the new t2.micro instance.

When the instance is stopped, and I try to change instance type, it will not display the t2.micro as an option.

I suspect it has to do with the new way the t2 instances virtualize (PV vs. HMV).

Anyone has an idea on how to perform the downgrade? Is it necessary to take a snapshot/image of the m1.small instance, and start a new t2.micro instance?

Here is a complete guide which you can use to change your existing PV instance to HVM instance. Just follow the steps carefully and you would be able to do it. Create an Image of your existing instance before you follow the guide
