It isn't the job of portupgrade, but it is a job that portupgrade can
handle.  Take a look at pkgtools.conf.  In mine, I've got:

  BEFOREDEINSTALL = {
    # Automatically stop the service for each package that has a
    # rc script enabled
    '*' => proc { |origin|
      cmd_stop_rc(origin)
    },

    # Stop postfix
    'mail/postfix*' => localbase() + '/sbin/postfix stop',
  }

I have a similar setup further down:

  AFTERINSTALL = {
    # Re-enable the X wrapper
    'x11-servers/XFree86-4-Server' => sprintf(
     'cd %s/bin && if [ -x Xwrapper-4 ]; then ln -sf Xwrapper-4 X; fi',
     x11base()),

    # Automatically start the server for each package that
    # installs a rc file enabled
    '*' => proc { |origin|
      cmd_enable_rc(origin)
    },

    # Start postfix
    'mail/postfix*' => localbase() + '/sbin/postfix start',
  }

I've only made a few additions to the pkgtools.conf that comes with
portupgrade.
