I recently upgraded two machines from 2.1.0-RELEASE to 2.1.5-STABLE. I
used CTM and it was actually quite painless. You just have to download
20-25 megs, run it through CTM, and that'll give you a new source tree. Do
a "make world" (should go down to single-user for this) and compile a new
kernel, and you're done. 

Be sure to consult the handbook for details.
