Quite a few of the properties have changed from 1.2.x to 1.4.x.
Also, the way properties are set for different graphical objects
(also called grobs in the documentation) has changed.
The first step to update your files is to run 'convert-ly -e file.ly'
but unfortunately it cannot handle all the changes, for example the
noteheadstyle property. I recommend that you take a look at the
example file input/regression/note-head-style.ly. The general 
principles of the new property setting mechanism is described in the
tutorial and in the chapter Tuning Output in the reference manual.
The list of the actual properties is not in the main printed manual 
but is available in the HTML documentation if you click on 
lilypond-internals.

Don't worry, very few features from 1.2.x have disappeared but there
are lots of new possibilities. The regression-test document gives a
nice overview of some of the old and new features.
