Preparing for Upgrades of View Composer Only

If you are upgrading only View Composer and are not upgrading VirtualCenter Server, you must perform the

following tasks:

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

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

Back up the VirtualCenter or vCenter Server database and the View Composer database.

For instructions on performing a database backup, see the documentation from your database vendor.

Verify that the database is compatible with View Composer 2.5.

View Composer supports a subset of the database servers that vCenter Server supports. If you are already

using vCenter Server with a database server that is not supported by View Composer, continue to use that

database server for vCenter Server and install a separate database server to use for View Composer and

View Manager database events.

Make a copy of the folder that contains SSL certificates.

This folder is located at

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

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.

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 4.5.

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