If you have installed Orchestrator 4.1.x with the vCenter Server 4.1.x installer on a 64-bit machine, you can upgrade to the latest version of Orchestrator by upgrading your vCenter Server on the same machine. The vCenter Server 5.0.1 installer detects the previous version and the installation path.

This procedure requires downtime for the Orchestrator and vCenter Server system that you are upgrading. You do not need to power off virtual machines.

Verify that the vCenter Server upgrade prerequisites and database upgrade prerequisites are met. For more information about preparing for the upgrade of vCenter Server, see the vSphere Upgrade documentation.

Verify that you know the correct port numbers to use. For a list of required ports, see the vSphere Installation and Setup documentation.

Download the vCenter Server 5.0.1 installer from the VMware Web site.

Back up your vCenter Server environment. For more information, see the vSphere Upgrade documentation.

Log in as Administrator on the Windows machine on which you are performing the upgrade.


Stop the Orchestrator Server and the vCenter Server services.


Click Start > Programs > Administrative Tools > Services.


In the right pane, right-click VMware vCenter Orchestrator Server and select Stop.


In the right pane, right-click VMware vCenter Orchestrator Configuration and select Stop.


In the right pane, right-click VMware VirtualCenter Server and select Stop.


Start the vCenter Server installer.

In the software installer directory, double-click autorun.exe.


Select vCenter Server™ and click Install.


Follow the prompts in the installation wizard to choose the installer language, agree to the end user patent and license agreements, enter your user name, organization name, and license key.

If you omit the license key, vCenter Server will be in evaluation mode, which allows you to use the full feature set for a 60-day evaluation period. After installation, you can enter the license key to convert vCenter Server to licensed mode.


Select the DSN.

This page appears if the installer is unable to determine the DSN for the database to be upgraded. The DSN must be a 64-bit DSN. Depending on the database type, the DSN might already be selected, or only one option might be available.


Specify the database user name and password for the DSN and click Next.

You can omit the database user name and password if the DSN is using Windows NT authentication.

If you specify a remote SQL Server database that uses Windows NT authentication, the database user and the logged-in user on the vCenter Server machine must be the same.


Select whether to upgrade the vCenter Server database.

Select Upgrade existing vCenter Server database to continue with the upgrade of vCenter Server.

Select Do not upgrade existing vCenter Server database if you do not have a backup copy of your database.

You cannot continue with the upgrade.


Select I have taken a backup of the existing vCenter Server database and SSL certificates and click Next.


Select how to upgrade vCenter Agent and click Next.




vCenter Agent is upgraded on all hosts in the vCenter Server inventory.


All hosts are disconnected from vCenter Server. To upgrade vCenter Agent, reconnect the host to vCenter Server.

Select this option if one of the following situations:

You need to control the timing of vCenter Agent upgrades on specific hosts.

The number of hosts in the vCenter Server inventory is large, and you anticipate that upgrading vCenter Agent on all hosts would negatively affect vCenter Server performance.

vCenter Agent is installed on each host in the inventory to enable vCenter Server to manage the host. vCenter Agent must be upgraded when vCenter Server is upgraded.


Set the login information for vCenter Server.



SYSTEM Account

Select the Use SYSTEM account checkbox, type the fully qualified domain name of the vCenter Server host, and click Next. You cannot use the SYSTEM account if you are using the bundled database or SQL Server with Windows authentication.

User-specified account

Deselect the Use SYSTEM account checkbox, type the account password and the fully qualified domain name of the vCenter Server host and click Next.


Select a folder to install vCenter Inventory Service.


The folder size might grow large.


Specify the port numbers to use or accept the port numbers that were used in the previous vCenter Server installation and click Next.


Select the amount of memory to allocate to the vCenter JVM in Tomcat, according to the number of hosts in your environment.

You can adjust this setting after installation if the number of hosts in your environment changes.


In the Ready to Install the Program page, select the check box to enhance the number of ephemeral ports available for transactions and click Install.


Click Finish.


Start the Orchestrator configuration service and log in to the Orchestrator configuration interface.


On the Database tab, update the database by clicking Update database.


Reimport the SSL certificate for the licensed vCenter Server and start the Orchestrator server.

For more information about importing the vCenter Server SSL certificate, see Import the vCenter Server SSL Certificate.

You upgraded vCenter Server and the Orchestrator client and server components. The existing Orchestrator configuration is preserved.
