How to downgrade a AWS EC2?

amazon-ec2

Solution

I think the best way is:

- Snapshot the volumes from the current instance.

- Create the new small type instance

- Use the snapshot(s) to create a replica of your existing volumes.

- Attach the new volume(s) created to small instance.

- Test it and switch ElasticIP to the new instance if everything is working ok.

Problem

I have an Amazon Web Service EC2 virtual server large type. Now I want to downgrade it to small type. I want to keep the hard disk information but just download the configure of the server. The main reason is to save few bucks. How can I do this? I think I should: - stop the current instance. - detach the volume from the current instance. - terminate the instance. - recreate a new small-type instance from scratch. - attach the volume to the small-type instance. I am not sure whether this is the correct way to do the downgrade or they have some formal way to do it. I tried to look up from the doc but couldn't find anything useful. I think someone here must be able to help me. Thank you very much.
