how can I move redhat licency from one server to another (new one)?

I've decided to upgrade my server.
I have active self-support RHEL subscription.
Can I use it on a new server?
How should I do this?

1. Install RHEL on a new server.
2. Unsubscribe old server and uninstall RHEL.
3. Subscribe new server.

Should I do something like this? Will it work? Or I have to buy new subscription for a new server?
