"They can keep their existing RHEL servers in place and simply switch to Oracle support, and they can install RPMs from Oracle's repositories on their RHEL servers without a hitch."
It's worth nothing that - unless you want to pay for support twice - this would violate the all-or-nothing clause. If a RHEL system is out of support you need to shut it down or otherwise all of your other currently employed RHEL instances will be out of support too. So no, no can't just leave the RHEL installation in place and switch to Oracle support.
