Upgrade Considerations
To upgrade to the current version of VCM, you must have version 4.11.1 or later installed and running.
Detailed upgrade procedures are provided in the VCM Installation and Getting Started Guide.
Configuring a 64-bit Operating System for a VCM Installation
To prepare your 64-bit system for a successful VCM installation, complete the procedures in the order
they are presented.
You must check each procedure against your system to ensure that all of the necessary components are
properly installed and configured.
Install and Configure a Windows Server 2008 R2 Operating System
Install the correct operating system on your Collector and verify that the settings are configured for VCM
operation. See "Sizing Impacts on Software Requirements" on page 25 to determine whether you require
the Enterprise or Standard Edition.
1. After you install the operating system, confirm that the computer name settings for your Collector
machine meet the required naming convention for VCM.
The computer name must be a valid DNS machine name with no underscores. Verify that the name is
correct before you proceed. If you attempt to change the machine name after the machine is identified
as a Collector, problems may arise with VCM, SQL Server, and SQLServer Reporting Services.
2. Verify that the person who performs these procedures uses a domain account with local administrator
rights.
3. Install Microsoft Windows Server 2008 R2.
Configure the Operating System Locale Settings
Verify that your Windows Server Locale Setting is configured correctly for a VCM installation.
1. In Windows Explorer, select Start > Control Panel > Clock, Language, and Region.
2. Click Region and Language.
3. In the Region and Language dialog box, click the Administrative tab and verify that the Language for
non-Unicode programs area displays English (United States).
Set the Terminal Services Mode to Remote Desktop for Administration
If Terminal Services are enabled, use the following procedure to verify that your Windows Terminal
Services setting is configured correctly for a VCM installation.
1. Select Server Manager > Roles > Remote Desktop Services.
2. Select Remove Role Services.
3. Clear the Remote Desktop Session Host setting and follow the online instructions.
Enable DCOM
DCOM (Distributed Component Object Model) is a protocol used to interact between application
components across Windows machines. Windows operating systems include DCOM.
To interact locally with Collector components, VCMCollectors require DCOM, which provides an option
to manage Windows VCM managed machines.
