Move a single host out of a cluster

We downsized one of our offices from two hosts in a cluster, to a single host.  I would like to move the last host that is in the cluster for that datacenter to reside under the datacenter itself, as there would be no HA or DRS functionality needed.  Then remove that cluster.

What is the process to do this so that interruptions to clients and risk to the health of the site is minimized.  Is this step even worthwhile?  Should all datacenters have a cluster even if there is only one host?

For moving a host out of a cluster you need to place it into MM so shutdown the VMs or perform a (s)vMotion.

In the past there was a benefit using a cluster also when only having one Host and this was "EVC".  Today there is also EVC on VM level but i never have configured it.

If you would like to use autom. Startup/Shutdown leave the Host as standalone without a Cluster.
