I clarified this with Tribe29 because we have an environment with ~300 sites on 1.6 and we need to upgrade to 2.0 and we cannot do it in one big step because the risk is to high to stop monitoring globally for a longer time.
The WERK´s are always not clear to what versions it really applies. I had opened already a bunch of tickets to clarify this because you cannot be sure.
