HA on KepserverEX

Hi Developers,

What are the HA features for KepserverEX ? 

The current scenario is that we have defined channels, devices and data tags in a single Kepserver and its now connected to the Thingworx composer. Now we're looking for fail safe scenarios on the Kepserver machine. I couldn't find documents for this.

I came across link and learnt about Redundancy Master. I'm didn't quite get how to use this and this document seems to be outdated. We're currently using TWX_Industrial Connectivity 8.3. 

Please suggest some useful guides.

Thanks and Regards,
