Remove host from vcenter

Hi,

I am upgrading my current ESX 3.5 environment to ESXi 4.1. Both environments have separate vCenters. The 3.5 one has no cluster, only a datacenter where hosts reside. For the upgrade I want to remove the host(s) from the old vCenter and import the host to the new 4.1 vCenter environment, but still use the old vCenter as the license server for the 3.5 hosts until they are ready to be reinstalled to ESXi 4.1. When I was about to remove one of the hosts from the 3.5 vCenter I received a prompt saying "Removing this host will also remove all of its virtual machines and resource pools. Are you sure you want to do this?" Does this actually interrupt or remove any VM's on that host or does this message mean remove so that it is no longer shown in the old vCenter? I found several different topics on this and with a few different answers.

Appreciate the replies.
Thanks.

Thank you, so basically what you are saying is that you can right-click and click remove on a host without disrupting any VM functionality on that specific host, but things like statistics and other will be lost from vCenter?
