How to compare Authoring & already promoted Live content? - Endeca Experience Manager

Currently there is no tool in Endeca to compare content between Authoring & Live instance.
Here is the workaround options:

Download content from Authoring Instance:  
http://localhost:8006/ifcr/sites/CRS.all.zip

Download content from already promoted Live Instance:
http://localhost:8006/ifcr/sites-live/CRS.all.zip 
 OR   
opt/app/endeca/MDEX/6.5.1/bin>export_config.sh host port (Live Dgraph host and port values )
