How to find out what’s new in OM12 for PowerShell
This week I started to play with Windows 8 and of course one of the first things I looked for was PowerShell 3.0 
And then I found a great blogpost on the PowerShellMagazine website by Shay Levy where he shows how find all the changes between the two versions of PowerShell (v2 and v3).
That’s when I thought why not use the same approach for finding the changes between the OpsMgr 2007 R2 PowerShell Commands and the OM12 PowerShell Commands.
This is the script I slightly modified to get it to work for OpsMgr 2007 and OM12.
# Compare differences OpsMgr 2007 PowerShell Commands and OM 12 PowerShell Commands. # Idea and initial script from Shay Levy on PowerShellMagazine.

Most of the changes are changes in the noun naming convention Example: Get-Alert is changed in Get-SCOMAlert.
Have fun!
