Hi Alex -
Happy to provide a bit more detail here.
As Dan pointed out, the WPM RC will be out next week. So if you wait until then and install all the RCs together, you’ll be good. If you can’t wait and want to install RCs that will put you on an upgraded Core while still keeping past versions of WPM (2.1 or 2.0.1), for now you will see a few resources error if you’re running on anything before Server 2012. It won’t corrupt the WPM install entirely.
Hope that helps.
