What you want to do is a cvsup (Mathew Seaman recently pointed out csup
that is supposed to be part of the system, but I don't seem to have it
on the machine I am presently on running 6.1) so you would have to install
cvsup from ports (/usr/ports/net/cvsup  or  /usr/ports/net/cvsup-without-gui)
if you need it.

I just posted a basic rundown on doing this (but with slightly different
numbers) just a couple days ago.   You might want to check the questions
archive.    Briefly, you install cvsup (if not already installed); run
the cvsup (or csup if you have it) using a supfile set for
  *default tag=RELENG_6_2
(I will append my working supfile at the end.  It is a simple one)
Then build and install everything.
Do this stuff in a script(1) session to preserve messages and warnings.

  cvsup -g -L 2 /etc/supfile62
Check out /etc/group  and  /etc/passwd  files to make sure there are
no conflicts or important changes.  Then build stuff.
  cd /usr/src
  make buildworld
Edit/create your kernel config if needed,  Then:
  make buildkernel KERNCONF=GENERIC   (or your own kernel config)
  make installkernel  KERNCONF=GENERIC  (or your own kernel config)
Then reboot to single user.
  fsck -p         For good measure
  mount -u /
  mount -a
  swapon -a
  cd /usr/src
  make installworld
Take a look at things to see if everything is OK, especially make sure
you have enough disk space.   Then run mergemaster
  mergemaster -cv

After this, reboot to a running system and check your config files
and other things.   Then install the ports and other stuff you want.

It preserves some things, but I am not sure all the details.

Probably they need to be reinstalled or updated, or at least rebuilt
with the latest libraries, etc.  It is best to assume so, even though
some might still work fine.    

Note that the supfile I show updates both the system and the ports
tree in one swell foop..

Note also, that this should be no problem going from one 'minor' version
level to a couple down the line, within the same 'major' version level
such as  your 6.0 -> 6.2  but I am much less convident crossing 'major' 
version levels such as 5.x -> 6.x and do a complete reinstall for those.

A supfile for going from 6.0 to 6.2.
Note, I keep my supfile in /etc and name it with the OS version which
accounts for the  cvsup -g -L 2 /etc/supfile62  command & arguments as above.
Ports don't have branches in the way the system source does, thus
the line for ports is:    ports-all tag=.    Same for doc.
