Preparing for a Horizon View

Upgrade 4

Before you start the upgrade process, you must review system requirements for the new version, back up

databases, take snapshots of virtual machines that host server components, and document configuration

settings.

This chapter includes the following topics:

“Preparing vCenter Server and View Composer for an Upgrade,” on page 21

“Preparing View Connection Server for an Upgrade,” on page 23

“Prepare to Upgrade or Reinstall a Security Server,” on page 24

Preparing vCenter Server and View Composer for an Upgrade

Because vCenter Server and View Composer are often installed on the same virtual or physical machine,

some preparation tasks apply to both.

Preparing for Upgrades That Include vSphere

If you are upgrading vCenter Server in addition to upgrading to Horizon View 5.2, you must consult the

VMware vSphere Upgrade Guide and perform the following tasks in the following order:

1 Verify that the virtual or physical machine meets the system requirements for the version of

vCenter Server that you want to upgrade to.

For example, vCenter Server 5.0 and later versions require two CPUs and must run on a 64-bit

operating system. Because View Composer 2.6 was supported on 32-bit operating systems, upgrading

might mean that you must upgrade vCenter Server and View Composer to a different machine.

2 Verify that the virtual or physical machine on which the current View Composer is installed meets the

security requirements for the new version.

See “Upgrade Requirements for View Composer,” on page 15.

3 Verify that the server on which vCenter Server is installed has a CA (certificate authority)-signed SSL

server certificate installed and configured. After you upgrade View Connection Server, if

vCenter Server does not use a CA-signed certificate, the default self-signed certificate is shown as

invalid in View Administrator, and a message indicates that vCenter Server is unavailable. For

information about replacing the default certificate for vCenter Server, see the vSphere Examples and

Scenarios document.

4 If vCenter Server is installed in a virtual machine, take a snapshot of the virtual machine.

For instructions on taking snapshots, see the vSphere Client online help.

5 If the computer name is longer than 15 characters, shorten the name to 15 or fewer characters.
