Upgrade Esx Hosts And Virtual Machines; Upgrade Esx 3.5 Hosts And Their Virtual Machines - VMware View Manager 4.5 Upgrade Manual

What to do next
If you upgraded vCenter Server, perform the post-upgrade tasks described in the vSphere 4.1 Upgrade Guide.
At your next maintenance window, continue with the VMware View upgrade. See

Upgrade ESX Hosts and Virtual Machines

Upgrading ESX hosts and virtual machines to vSphere is the most time-consuming aspect of this middle phase
of a VMware View upgrade.
Upgrading from ESX 3.5 involves more steps than upgrading from ESX 4.x because the upgrade includes
upgrading the virtual hardware version of the virtual machines.

Upgrade ESX 3.5 Hosts and Their Virtual Machines

Upgrading ESX 3.5 hosts and virtual machines involves upgrading the host, the virtual machine virtual
hardware version, and the version of VMware Tools on the virtual machines. If you use View Composer, the
upgrade includes turning on vSphere mode.
This procedure provides an overview of the tasks you must perform during the second and subsequent
maintenance windows. To complete some of these tasks, you might need step-by-step instructions found in the
vSphere Upgrade Guide and the VMware View Administrator's Guide.
Prerequisites
Complete the procedure described in
n
page 21.
Perform the ESX preparation tasks listed in the vSphere Upgrade Guide.
n
Verify that you have the correct license key for vSphere if you are upgrading Virtual Infrastructure
n
components to vSphere.
Verify that all ESX hosts are members of a cluster. If you want to upgrade a standalone ESX host, place it
n
in a single-host cluster. If the ESX host is not part of a cluster, you might not be able to enable vSphere
mode for View Composer.
Procedure
1 Upgrade ESX hosts to vSphere 4.1, cluster by cluster.
For instructions, see the vSphere Upgrade Guide. If you have many clusters, this step could take several
maintenance windows to complete. Upgrading ESX hosts includes the following tasks:
a Use VMotion to move the virtual machines off of the ESX host.
b Put the ESX host into maintenance mode.
c Perform the ESX upgrade.
d Use VMotion to move the virtual machines back onto the ESX host.
e Perform post-upgrade tasks for ESX hosts.
Every ESX host must be a member of a cluster, as mentioned in the prerequisites.
2 If an upgraded ESX host does not reconnect itself to vCenter, use vSphere Client to reconnect the ESX host
to the vCenter Server.
3 If you use View Composer, after all ESX hosts are upgraded, on the vCenter Server host, restart the
View Composer service.
