How to change control-plane-endpoint option in a live cluster?

Question

I deployed a cluster (on premise) as proof of concept, using this command:

sudo kubeadm init --upload-certs --pod-network-cidr=x.x.x.x/16 --control-plane-endpoint=x.x.x.x.nip.io

Now, i need to change the endpoint from x.x.x.x.nip.io to somename.example.com. How can i do this?

Based on the documentation and very good answer (which is about switching from simple to high availability cluster and it has steps about adding --control-plane-endpoint), there's no easy/straight-forward solution to make it.

Considering risks and difficulty it's easier to create another cluster with a correct setup and migrate all workflows there.
