Although its not recommended to do this, it can be done. It basicaly
comes down to following the manual (without rebooting into single
usermode) and be very very carefull. Read everything you need to read,
run every command you need to run and have someone sitting there in case
it goes wrong.

Note: I've never done this on a busy system.
