I plan to upgrade helpdesk connector in the development system. Do I need to uninstall V184.108.40.206 first or if I can simply do the upgrade on top of V220.127.116.11?
Release : 4.2
Component : Service Operations Insight (SOI) Manager
There's no upgrade for the NIM Helpdesk, you would need to uninstall and install the new one.
Make sure you backup the \soi\tomcat\lib\resources\helpdesk.properties for reference
