I don't know if it's the best method, but in Windows I simply rename the  
old
lilypond directory to e.g "C:\Program Files\Lilypond_2.12 and install the  
new
one to C:\Program Files\Lilypond.

when I want to use 2.12, I rename the new directory to \Lilypond_2.13 and  
the
old to \Lilypond, i.e, the "active" installation is always C:\Program  
Files\Lilypond
and the "inactive" ones are renamed.

It's a bit hairy, but it does the trick for me...
