The complete instruction on how to do a WLC upgrade can be found in the Release Notes.
I can't stress how important reading the Release Notes carefully because it may contain very useful information about whether or not the upgrade will be successful.
Aside from Open and Fixed Caveats, there are versions where one can upgrade to DIRECT and others can't.
