yum is almost unusable as packages has mostly the same version in RC1
and final.

One solution is to compare RPM packages from RC1 and final and use 
"rpm -Uvh --force package" to replace changed packages.

The second solution is to comapre build dates of installed packages and
build dates of final packages and replace with --force as above. You may
use this script:

#!/bin/bash

for i in $(rpm -qa --qf "%{BUILDTIME}:%{NAME}-%{VERSION}-%{RELEASE}.%{ARCH}.rpm\n"); do
  BUILDED=$(echo $i | awk -F: '{print $1}')
  NAME=$(echo $i | awk -F: '{print $2}')
  FULLNAME="/path/to/final/RedHat/RPMS/$NAME"
  if [ -e $FULLNAME ]; then
    # replace only when build dates are different
    if [ $(rpm -qp --qf "%{BUILDTIME}" $FULLNAME) -ne $BUILDED ]; then
      echo $NAME
    fi
  fi
done

This script does not solve packages with changed names (this could solve
yum for you).
