Want to know the shutdown procedure once the vCenter is running on virtual appliance

Hi,

Currently vCenter server (vCenter / SSO / SQL on same server) is running on physical machine. And I am planning to upgrade and migrate it to virtual appliance.

Thus I would like to know the shutdown procedure once the vCenter is running on virtual appliance.

Under current environment (VC server on physical machine), shutdown procedure is:

1. Shutdown all VMs
2. Shutdown all VM hosts
3. Shutdown vCenter server

Please advice.

Thanks
