Good, but you need not boot it.  You can check the release date for 4.6 
and 4.4 to find which one it should.  If you don't care about running a 
kernel out of sink with your world then by all means do it.  Be sure to 
back up data first and I would recommend going into single user mode to 
help avoid a possible panic or other strange behavior.
