Question:

Can we install secondary hub in cluster?

Environment:
UIM 8.5 Primary, secondary are on windows 2012 R2 OS
Answer:

This is not currently considered supported - we have not tested or certified running secondary hubs on a cluster, and there are potential side-effects related to hub-to-hub communication which may be of concern. 

The only supported method for high-availability of a secondary hub is the use of the UIM HA probe:
