Whee, that's a lot of work. With EL6 you have 'yum distro-sync' at your beckon call; a patch to add a 'distro-sync full' exists that goes as far as checking checksums, which probably has a greater chance of working correctly.
On an EL6 it should be as simple as changing the repositories and issuing yum distro-sync (with some rhn-specific steps depending on the direction of the cross-grade, though). But I say 'should' for a reason, as I've not tried. Yet. I likely will try this once C6 is out, since I have a 32-bit system to cross-grade (want to use the subscription entitlement on a different machine).
