Re: Moving to ES from older RedHat

Can someone tell me if "support is not included" means "we do not

Both.

The product can't do it, because it has no upgrade option in the
installer. Since this is the first Red Hat Enterprise Linux ES and also
since it's code base differs too much from the Red Hat Linux line to
guarantee any degree of success upgrading, upgrading isn't an option. 

Which also means we don't support the configuration. You *could* tweak
it to make it upgrade, but the modifications would make it no longer
RHEL ES and therefore unsupported (though it may well be perfectly
functional). That would likely take longer than a straight install.

So the thing to do (generally) is migrate data somewhere safe, install,
and bring the data back in which is supportable via tech support. The
support matrix (depending on which ES you bought) is here:
