I ran into some MP’s that after importing into a new environment found out the hard way will break your install.
Service level objects
Sadly there is nothing documented at MS to advise against importing these, And the system will actually let you import them. However if you do import them, you will get unexpected results. For instance, when I imported the SLO MP, my system would not allow me to create a AD connector. I had to actually open a case with MS to undo the damage caused by importing these MPs.
