I have a HP Gen8 for lab purposes, which acts as an ESXi 5.5 host. All running well so far, with a few DC's, SQL servers and SCCM server etc on a single domain. However I now have a new AD migration product which I would like to test. I have stood up a new DC VM on a separate IP addressing scheme however from a networking point of view, how do I configure this? Do I create a separate vSwitch and connect the new DC to it? The server on which the new product resides must be able to communicate and authenticate with both domains.
