In general, the only safe method is to stop the service before deinstall and 
to start it after the upgrade. If a service must not be interrupted, it 
probably shouldn't be updated in first place.

Quite some time ago one daemon always ceased to work for me after a 
portupgrade. I've added the following lines in my pkgtools.conf (taken from 
the sample file) and everything worked fine afterwards.

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

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