Thanks for the pointer. Checked my DHCP-cluster right now, looks good.

The rebuild of the network was cancelled this week because of 
Covid-related issues: they have *more* work now and can't risk the 
downtime right now (not even the planned "one floor only mode" day).

So I have more time to plan and test.

I might plan that maintenance window, and turn off DC1, yes.

No relevant shares on that machine, only one for me, the admin ...
