Hello @rbenson09,
You can check the reference about the upgrading from the install guide here.
https://docs.mcafee.com/bundle/application-change-control-8.3.x-installation-guide-windows/page/GUID...
You can do the upgrade on Enable mode but I recommend the Update mode in order to avoid unexpected block while upgrading it.
I hope this helps.
