If you've got RHEL running in an environment, and you want the RHSA bundle, you can pay for access to the RedHat network, and get it done easily. Otherwise, you *MIGHT* be able to get a list of ALL the packages that are updated from RedHat's site, and download/upgrade them all, one by one. And you probably won't get them all, since the update cycle won't match between CentOS and RHEL.
If you're not going to pay for RHEL, it's best not to use it, and use something community-supported.
