SCOM: Compare MP's between Management Groups with PowerShell

A short blog post about comparing management packs between SCOM environments I know there are tools available to compare management packs, but that's no fun. Creating this compare script with PowerShell to accomplish the same didn't cost me that much time. And of course, doing it yourself with PowerShell is just more fun. So here it is.

This script gives you a gridview with the differences, as well as an CSV output file.
