Mohammed, great so just to be sure I understand fully...if I follow Question 1 and keep the same name and IP I will still need to remove the original vCenter 4.1 off the domain because once I build the new one AD/DNS will not allow me to use that name if it's still tied to the original server, so stopping the service alone is not going to prevent the use of the same DNS name on the network...correct?
Question 4: So is part of the process via Update Manager when it comes to upgrading the VMs to new VMware Tools & hardware 9 to move them into a new VMFS-5 datastore? I know you can upgrade your existing VMFS-3 datastores and the documentation says that would be the last step in a standard upgrade but in my case I'm going to have these created separate...just wanted to be certain that it will allow me the option to move them into a new VMFS-5 datastore not upgrade the existing ones?
