Moving ESXi virtual machines
If you ever need to transfer ESXi VMs between hosts, use the VMware standalone converter. It’s most efficient if you give the VMkernel on each box a dedicated NIC. In this case, both source and destination boxes have vmkernel/vmnic0 go to the same gig switch and vmnet/vmnic1 to a different one. Even the 150Gb machine didn’t take particularly long to transfer.
When you get to the last page (configuration) you may want to click thru the “editable” sections to adjust things like nic assignment, memory, provisioning, etc, before clicking Finish.
