If we waited three years, we would still be facing us.
The clusterware version is 11.2.0,3. When we first discussed the RedHat 6
upgrade, I it may be possible to drop the first node from the cluster,
installing the upgrade, add the node back using addnode.sh, then same thing for
nodes two and three. This process definitely does not work.

If you are supported by RedHat, you will have to reinstall afresh, else redhat
will wash their hands as far as those three systems are concerned. They don't
support upgrade between major versions.
You can try it though. Depending on what installed, changes that have been
made, you could just be lucky. I would not go that route though. You are
highly likely to break your system or encounter funky issues going forward.
Why do you need upgrade though? RHEL5 is supported for another 3 year. And
unlike RHEL4, RHEL5 is mature.
The only distribution that upgrade reliably is Debian, everything else, it's
trial and error.
