Installation guide

4 If you use View Composer, turn on vSphere mode.

vSphere uses a new API to achieve performance improvements.

a Verify that all ESX hosts in a cluster are running vSphere 4.1.

b Log in to View Connection Server and turn on the desktop pool setting called Use vSphere mode for

View Composer.

For instructions, see the VMware View Administrator's Guide.

c On a parent virtual machine upgrade View Agent to 4.5, create a test desktop pool, and verify that

vSphere mode is used.

This new test desktop pool uses the new View Composer API and as a result, does not create a source

linked clone from the replica. If you use vCenter Server to watch the virtual machines being created,

you see that a replica is created from the parent, but not a source-lc virtual machine.

5 Upgrade VMware Tools and the virtual hardware on all parent virtual machines, virtual machine

templates, and virtual machines that host View server components such as View Connection Server

instances.

a Plan for down time, as described in the vSphere Upgrade Guide.

Each virtual machine must be rebooted three times.

b Update VMware Tools, and upgrade the virtual machine hardware to version 7.

If you use vSphere Update Manager, you can update VMware Tools and then the virtual hardware

version in the correct order for all the virtual machines in a particular folder. See the vSphere Upgrade

Guide.

6 If you use full-clone desktops, on each virtual machine, upgrade VMware Tools and the virtual hardware

to version 7.

If you use vSphere Update Manager you can update VMware Tools and then the virtual hardware version

in the correct order for all the virtual machines in a particular folder. See the vSphere Upgrade Guide.

What to do next

Upgrade View Agent. See “Upgrade View Agent,” on page 38.

Upgrade ESX 4.0 Hosts and Their Virtual Machines

Upgrading ESX 4.0 hosts and their virtual machines involves fewer steps than upgrading from ESX 3.5.

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

Perform the following preparation tasks:

Complete the procedure described in “Upgrade View Connection Servers in a Replicated Group,” on

page 21.

Perform the ESX preparation tasks listed in the vSphere Upgrade Guide.
