You don't need to upgrade grub, I'm quite happily dual booting rhel6 GA
on a CentOS-5 system (using C-5 GRUB).
Only thing I did differently is the rhel6 /boot partition is mounted on
an ext3 partition whereas I _think_ the default might be ext4 which, as
a wild guess, is probably unsupported by CentOS-5 GRUB ?
The rest of the system is quite happily sitting in an ext4 partition
using md raid on lvm.
