I have googled this on the web and also searched for the answer on StackExchange but I can't find a clear set of instructions for removing and deleting a super admin user!
I'm performing some admin tasks on a multisite with 100+ sites and need to remove/clean up some old developer accounts within the dashboard.
I go to network > users and see a list of super admin and cannot remove any of them. I can disable their accounts (which is a logical first step).
Do I need to individually remove them from each of the 100+ sites and then I can remove their account from the WPMU? Alternatively, is there a quick/simple way to demote their role to subscriber from super admin?
