Upgrade ESX/ESXi Hosts and Their

Virtual Machines 6

Upgrading ESX/ESXi hosts and virtual machines is the most time-consuming aspect of this middle phase of

a Horizon View upgrade.

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 VMware vSphere Upgrade Guide and the VMware Horizon View Administrator's Guide.

For details about which versions of Horizon View are compatible with which versions of vCenter Server and

ESX/ESXi, see the VMware Product Interoperability Matrix at

http://www.vmware.com/resources/compatibility/sim/interop_matrix.php.

IMPORTANT To use the space-efficient disk format feature for linked-clone pools, you must upgrade

vCenter Server, ESXi hosts, virtual machines, and the VMware Tools software in the virtual machines to

VMware vSphere 5.1 or later.

Prerequisites

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

page 34.

Perform the ESX/ESXi upgrade preparation tasks listed in the VMware vSphere Upgrade Guide.

Procedure

1 Upgrade ESX/ESXi hosts, cluster by cluster.

For instructions, see the VMware vSphere Upgrade Guide. If you have many clusters, this step could take

several maintenance windows to complete. Upgrading ESX/ESXi hosts might include the following

tasks:

a Use VMotion to move the virtual machines off of the ESX/ESXi host.

b Put the host into maintenance mode.

c Perform the upgrade.

d Use VMotion to move the virtual machines back onto the host.

e Perform post-upgrade tasks for ESXi hosts.

Every host must be a member of a cluster, as mentioned in the prerequisites.

2 If an upgraded host does not reconnect itself to vCenter Server, use vSphere Client to reconnect the host

to vCenter Server.

3 If you use View Composer, after all ESX/ESXi hosts are upgraded, on the vCenter Server host, restart

the View Composer service.
