Horizon View Upgrade Overview 2

Upgrading an enterprise Horizon View deployment involves several high-level tasks. Upgrading is a

multistage process in which procedures must be performed in a particular order. You upgrade View

Composer before upgrading View Connection Server and the other Horizon View servers.

During an upgrade, Horizon View does not support View Composer provisioning and maintenance

operations, local mode operations, or View Transfer Server publish operations. Operations such as

provisioning and recomposing linked-clone desktops, checking out or checking in desktops, and publishing

View Composer base images are not supported during the transitional period when any Horizon View

servers are still running the earlier version. You can successfully perform these operations only when all

instances of View Connection Server, View Composer, and View Transfer Server have been upgraded.

You must complete the upgrade process in a specific order. Order is also important within each upgrade

stage.

NOTE This overview relates to upgrades for major, minor, and maintenance releases. For information about

patches, see Chapter 8, “Applying Horizon View Patches,” on page 55.

How many of the following tasks you need to complete depends on which components of Horizon View

you use in your deployment.

1 On the physical or virtual machines that host View Composer and vCenter Server, make backups and

temporarily halt certain scheduled tasks. See “Preparing vCenter Server and View Composer for an

Upgrade,” on page 21.

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.

2 On the physical or virtual machines that host View Connection Server instances, make backups and

record various configuration and system settings. See “Preparing View Connection Server for an

Upgrade,” on page 23.

3 If you use security servers, perform the tasks in “Prepare to Upgrade or Reinstall a Security Server,” on

page 24.

4 Upgrade View Composer on an existing Windows Server 2008 R2 host or, if you are running View

Composer 2.6 on Windows Server 2003, migrate to a new machine. See “Upgrade View Composer,” on

page 25.
