Scripting

I am currently in the process of decommissioning KACE from our environment.  Unfortunately, we are going with SCCM for the long haul.  I want to uninstall all Quest Kace Agents from our desktop environment before i completely shut down just to prevent any confusion or reporting from desktops going forward.  I inherited Kace and i'm not at all that familiar with the product.  I came into this two years ago in the middle of my first year before i was to be trained on the product the company wanted to move in a different direction.  The previous admin was versed in KACE but has since left the company.  I was hoping anyone can guide me or provided documentation on best practice for removing the agent from the desktops.  Silent uninstall would be best.   I'm sure i'm not the only one who has asked this request but I'm unable to find any documentation with specifics.  Any help would be appreciated.
