I upgrade in-place all of the time.  Let s and k be environment
variables set to binary/sets/ and binary/kernel/ in a release directory:

0 Update boot blocks.  Usually I skip this step, so I don't have any
  particular command(s) to recommend.  See installboot(8).

1 Backup the old kernel,

  cp /netbsd /netbsd.old

2 Extract the new kernel at /netbsd,

  gunzip < $k/netbsd-GENERIC.gz > /netbsd

3 Extract the modules.tgz,

  cd /
  pax -pe -rzf $s/modules.tgz

4 Reboot

5 Extract all of the sets except for etc.tgz and xetc.tgz,

  cd /
  pax -pe -rzf $s/base.tgz
  pax -pe -rzf $s/comp.tgz
  pax -pe -rzf $s/xbase.tgz
  pax -pe -rzf $s/xcomp.tgz

6 Update /etc/,

  etcupdate -s $s/etc.tgz -s $s/xetc.tgz
