Building a kernel from source on an enterprise system will almost surely break
something. A remote upgrade is possible, but you will need to test it
thoroughly on something like a vmware image or another piece of hardware that
you can access easily. You had the option to use vnc and do remote installs in
4.0, but I haven't tried it in 5. Here is a link that will take a little
testing and adjusting as it is for an upgrade to 4.
