Upgrading By Moving Powered Off Or Suspended Virtual Machines (Without Vcenter Server) - VMware ESX 4.0 - UPGRADE GUIDE UPDATE 1 Update Manual

You can install the vSphere Client on the same machine with your previous version of the VI Client. You
must have the previous version of the VI Client to connect to previous versions of VirtualCenter and ESX/
ESXi.
For a detailed description of the procedure, see
4 If your environment has vCenter Converter, upgrade it to the latest version.
5 If your environment has vCenter Guided Consolidation, complete the consolidation plan and then
upgrade it to the latest version.
6 If your environment has vCenter Update Manager, upgrade it to the latest version.
Procedure
1 Add ESX 4.0/ESXi 4.0 host to vCenter Server 4.0.
2 Add ESX 2.5.x or ESX 3.x/ESXi 3.5 hosts to vCenter Server 4.0.
3 Power off or suspend the virtual machines on the ESX 2.5.x or ESX 3.x/ESXi 3.5 hosts.
4 Move the virtual machines to the ESX 4.0/ESXi 4.0 hosts.
What to do next
1 Upgrade your virtual machines:
a If they are not already powered on, power on the virtual machines and upgrade to the latest version
of VMware Tools. This upgrade allows you to use the new features of ESX 4.0./ESXi 4.0.
b Power off the virtual machines and upgrade to the latest version of virtual hardware to take advantage
of the new virtual hardware. vSphere 4.0 supports some earlier virtual hardware versions. See Basic
System Administration.
The virtual machine upgrade process is different for ESX 4.0/ESXi 4.0. In earlier versions, you upgraded
the virtual hardware upgrade before you upgraded VMware Tools. For ESX 4.0/ESXi 4.0, you upgrade
VMware Tools before you upgrade the virtual hardware.
You can use either the vSphere Client or vCenter Update Manager to upgrade virtual machines. In a
clustered environment, VMware recommends that you use vCenter Update Manager . See the vCenter
Update Manager Administration Guide. If you are using the vSphere Client to upgrade virtual machines, see
Chapter 13, "Upgrading Virtual Machines,"
2 Upgrade your product licenses:
a Either your new license keys are sent to you in email, or you get them using the license portal.
b Apply the new license keys to your assets using the vSphere Client (or vCenter Server if you have it).
You must perform these tasks for each ESX 2.5.x host and the virtual machines on the hosts.
Upgrading by Moving Powered Off or Suspended Virtual Machines
(Without vCenter Server)
This scenario is known as a cold migration upgrade. When you use cold migration to move virtual machines
from one host to another host, additional downtime is required for the virtual machines.
This scenario assumes that the hosts do not have VMotion, VirtualCenter, or vCenter Server.
