How to properly shutdown a vmware vsphere environment

Hi Guys,
I'm administering a VMWare vSphere 6 cluster with 3 ESXi hosts.
All the storage has been configured using vSAN.
The vCenter is a VM Appliance.

I have to completely shut down all the environment for a maintenance process related to power issues.
I have to do this in a couple of hours so the sooner you reply the better.

So my question is:
What is the proper way to fully shutdown a VMWare vSphere 6 environment?

This is my guess:
I'm going to call my ESXi hosts 1,2, and 3.

1. Login to each vm and shutdown from the gues OS (Windows Server), leaving only the vCenter vm appliance running on ESXi host 1.
2. Login to vCenter and shutdown ESXi host 2 and ESXi host 3 (since there are no VMs running on them this should be a straight forward task.

This is where my guessing begins:

3. Connect directly to ESXi host 1 using VMWare Client and shutdown the vCenter appliance.
4. Use that same connection to shutdown ESXi host 1 (At this point this is the last ESXi host still running in the cluster).

Is this it?

Thanks.

Yes, that's exactly the process.

As for Step 1, there is no need to login to each VM, you can shutdown Guest from the vSphere Client connected to vCenter Server.

which saves you some time.

You can also select ALL VMs in vCenter Server, under virtual machines tab, select all, and hit he Short Cut Keys to Shutdown Guests, to do them all at the same time, just remember to exclude vCenter Server.
