| (http://docs.oracle.com/cd/E19455-01/806-7933/index.html) does?
| 
| In my past life as a Solaris sys-admin, I found this an extremely
| useful
| tool for upgrading and patching running systems, as well as for
| maintaining redundant boot environments on separate system disks for
| disaster situations.

Nothing really until BTRFS comes of age.  I suppose you could snapshot your LVM volumes before performing the upgrade but to my knowledge there is nothing similar to Live Upgrade for CentOS
