I have 2 ESX 3.5 Update 1 with about 10 to 15 VM's on them. I need to make a change to the hosts file as this host file has the original 192.168.x.x address instead of the new 10.10.x.x address. I know how to change it, my concern is what to do after I change it. On top of that I can shut down or reboot the ESX because the VM's have some critical guests on them. Please assist. Thank you.
