6 Make a copy of the folder that contains SSL certificates.

This folder is located at %ALLUSERSPROFILE%\Application Data\VMware\VMware VirtualCenter.

7 Document the IP address and system name of the machine on which vCenter Server is installed.

8 For all linked-clone desktop pools, disable provisioning of new virtual machines.

Because View Composer might be upgraded during a different maintenance window than its desktop

pools, provisioning must be postponed until both components are upgraded.

9 If any desktop pools are set to refresh the OS disk on logoff, edit the Desktop/Pools settings for that

pool and set Refresh OS disk on logoff to Never.

This setting prevents an error from occurring when the newly upgraded View Composer attempts to

refresh a desktop that has not yet been upgraded to View Agent 5.2.

10 If any desktop pools are scheduled to do a refresh or recompose operation, cancel these tasks.

Preparing View Connection Server for an Upgrade

Before you upgrade View Connection Server or before you upgrade any of the vSphere components that

View Connection Server relies on, you must perform several tasks to ensure that these upgrades are

successful.

Verify that the virtual or physical machine on which the current View Connection Server instance is

installed meets the system requirements for the new version.

See “View Connection Server Requirements,” on page 16.

If View Connection Server is installed in a virtual machine, take a snapshot of the virtual machine. If

you have a replicated group of View Connection Server instances, take a snapshot of only one View

Connection Server instance.

For instructions on taking snapshots, see the vSphere Client online help. If you ever need to revert to

this snapshot and if you have other View Connection Server instances in a replicated group, you must

uninstall those instances before you revert the master to the snapshot. After you revert, you can

reinstall the replicated instances and point to the instance you reverted.

You can label the snapshot Upgrade Preparation Phase.

Open View Administrator and document all the global settings and settings for desktops and pools:

Pools section and Desktops section in the Inventory tree, and the Global Settings section in the View

Configuration tree.

For example, take a screen shot of the applicable settings. If you have multiple instances of View

Connection Server in a replicated group, you need only document the settings for one instance.

Use the vdmexport.exe utility to back up the LDAP database.

For instructions, see the administration guide for your current version of the VMware Horizon View

Administration document. If you have multiple instances of View Connection Server in a replicated

group, you need only export the data from one instance.

Document the IP address and system name of the machine on which View Connection Server is

installed.

Determine if your company has written any batch files or scripts that run against the View database on

the View Connection Server instance, and if so, document their names and locations.

If you use load balancers for View Connection Server, document the configuration settings for the load

balancers.
