Reading through all the upgrade, limitations and known issues documentation, I got stuck on this:

In the R80.20 installation and upgrade guide it states that you need to do mdstop before running the pre-upgrade verifier.


I get cautious and paranoid when this needs to be done on a mds with multiple domains and gateways.


I couldn't find any explanation why this needs to be done and can it be avoided, if avoided what "scary-end-of-the-world" -issues will surface. Is it enough that Dashboard/ssh/Webgui connections to the mds and domains are blocked?
