How do you move VMware ESXi hypervisor to a different physical drive

matt1237 used Ask the Experts™
ESXi hypervisor is installed on a single disk datastore that I would like to take out of my server.  How can I migrate the ESXi hypervisor to the RAID datastore that I've already moved all my VMs to?  I want my server to will boot from the RAID datastore in the future?

Honestly, the easiest thing to do is just reinstall ESXi on the new RAID. Just document your configs and re-config your settings. If you have VMs on the same disk as your ESXi install, you'll need to copy them off to back them up. You can then copy them back after the reinstall and 'add them to inventory'.
