Say I decided that the domains I’d setup for my cert were not what I wanted after all.
e.g. perhaps I am not using some of them, I’ve transferred some to someone else, deleted some and have some redirecting to elsewhere.
But I still have some domains that I want to have https for.
Deleting the domains I don’t want is not straightforward, it seems: Remove domain not required from cert
So how could I completely remove all entries for the existing cert and simply start again?
