Removing a Node from a Cluster

[Boss]

Running PVE 8.1.3
I need to remove a node from the cluster, change the hostname & then add it back to the cluster.
I plan to move all the VMs off this node first.
The next step would be to remove the node from the cluster, however I can't find anything in the GUI to allow this?
While all the VMs are off this node, I was also planning to update PVE to 8.1.4 and then rejoin it to the cluster (with a new hostname).

Any thoughts on how I should perform this change?

Hi @bbgeek17 - thanks for the links. I did look at some of these previously, which is why I decided that I should move the VMs beforehand in case I had to delete the nodes folder manually. One point I'm still not sure about is the recommendation to perform a fresh install of PVE before adding it to the cluster again? All I want to do is rename the host before adding it to the cluster again.
