This is worth an experiment to have two different versions of Clarity on one server:
For example: version 14.x on C drive
Version 15.x on D drive.
The services name would be like app14, bg14, beacon14 and nsa14 for version 14.
The services name would be like app15, bg15, beacon15 and nsa15 for version 15.
App, NSA and Beacon ports would be different.
The corresponding Databases will be different.
Do we really need to set NIKU_HOME and Clarity_HOME, once the installations are configured and JVMs launched?
I hope this should work.
