Listen to the chorus. Test the upgrade. Buy, rent or steal some
hardware, set it up to match your current config and then perform the
upgrade and see what happens. Test that you can get back if you have
to revert halfway through. Find all the "faulty DBA" and "negligent
SysAdmin" problems before you start.
