   The above will allow to keep the old logstash-forwarder running and it can be slowly switched over to Filebeat.

  +=== New input plug-in for Logstash
  +
  +TODO
  +
  +
  +=== Other changes
  +
  +The following is a list of implementation changes that we don't expect to
  +affect your experience migrating from Logstash-Forwarder but that you should be
  +aware of. Please post GitHub issues if notice any regression from
  +Logstash-Forwarder.
  +
  +==== Packaging
  +
  +The packaging process for Filebeat uses the Beats infrastructure, so some
  +things like the init scripts are different from those that the
  +Logstash-Forwarder provided. Please post GitHub issues if you hit any issues
  +with the new packages.
  +
  +==== Publisher improvements
  +
  +Behind the scenes, Filebeat uses a sightly improved protocol for communicating
  +with Logstash.
  +
  +==== Logging
  +
  +Filebeat uses libbeat logging and can also log to a file instead of syslog.
  
positive.code: == Logtash-Forwarder to Filebeat Migration
  
  The following guide should help you to upgrade from the logstash-fordwader to filebeat.
  
  There are four major changes:
  * The config file was restructured and converted from json to yaml
  * The registry file which stores the state of the logstash-fowarder was renamed
  * Command line options were removed and moved to the confg file
  * Configuration options for outputs are inherited from libbeat. Details can be found https://www.elastic.co/guide/en/beats/libbeat/current/index.html[here]
  
  
negative.code: |Both options were removed as logging is part of the libbeat config.
