I am trying to upgrade the controlplane from 1.18 to 1.19. But after downloading the packages, when I run kubeadm upgrade apply v1.19.0, I get the error that admin.conf file is not found.
I couldnt locate the file under /etc/kubernetes.
Am i missing something here?
If I should be doing the upgrade hardway, where can I see the documentation as I dont remember seeing in the training.
