Not without pullint out one of *my* favorite tricks! Build a clean OS
image tarball, and use any live CD or kickstart or any other PXE based
tool you wish to partitioni the target disk, drop the tarball onto it,
tweak a few config settings as needed, run "grub-install" from inside
the new installation's chroot cage, and reboot.

It takes work to tun, but it is *much, much, much* faster than pulling
down RPM's and assembling the new environment from scratch. And
without the bulky and discarded "yum" metadata downloads it's much
more network efficient..

Install 6.5? There are significant library and kernel updates since SL
6.5, especially for the latest and greatest 10G network drivers.

Also, don't use any more of NetworkManager than you have to for servers.
