You must upgrade the database and configure all systems that have IaaS components installed. You can use these steps for minimal and distributed installations.

If you have multiple IaaS servers, perform the upgrade so that services are upgraded in the following order.



Finish the upgrade on one server before upgrading the next server that is running a Website service.


Manager services

Upgrade the active manager service before you upgrade the passive manager service.


DEM orchestrator and workers

Upgrade all DEM orchestrators and workers.



Finish the upgrade on one server before you upgrade the next server that is running an agent.

If you are using different services on one server, the upgrade updates the services in the proper order. For example, if your site has Website and Manager services on the same server, select both for update. The upgrade installer applies the updates in the proper order. You must complete the upgrade on one server before you begin an upgrade on another.


Right-click the setup file that you downloaded and select Run as administrator.


Click Next.


Accept the license agreement and click Next.


Type the administrator credentials for the vCloud Automation Center Appliance on the Log In page and click Next.

The user name is root and the password is the password that you specified when you deployed the vCloud Automation Center Appliance.


Select Upgrade on the Installation Type page and click Next.


Configure the upgrade settings.



If you are upgrading the Model Manager Data.

Select the Model Manager Data check box in the vCAC Server section.

The check box is selected by default. Upgrade the Model Manager data only once. If you are running the setup file on multiple machines to upgrade a distributed installation, the Web servers stop functioning when versions 6.0.1 or 6.1 do not match the version of the Model Manager data. When you have upgraded the Model Manager data and all of the Web servers, all of the Web servers should function.

If you are not upgrading the Model Manager Data.

Unselect the Model Manager Data check box in the vCAC Server section.

To preserve customized workflows as the latest version in your Model Manager Data.

If you are upgrading the Model Manager Data, select the Preserve my latest workflow versions check box in the Extensibility Workflows section.

The check box is selected by default. Customized workflows are always preserved. The checkbox determines version order only. If you used vCloud Automation Center Designer to customize workflows in the Model Manager, select this option to maintain the most recent version of each customized workflow before upgrade as the most recent version after upgrade.

If you do not select this option, the version of each workflow provided with vCloud Automation Center Designer 6.1 becomes the most recent after upgrade, and the most recent version before upgrade becomes the second most recent. For information about vCloud Automation Center Designer, see Extensibility.

If you are upgrading a Distributed Execution Manager or a proxy agent.

Enter the credentials for the administrator account in the Service Account section. All of the services that you upgrade run under this account.

To specify your Microsoft SQL Server database.

If you are upgrading the Model Manager Data, enter the names of the database server and database instance in the Server text box in the Microsoft SQL Server Database Installation Information section. Use a fully qualified domain name (FQDN) for the database server name.

If the database instance is on a non-default SQL port, include the port number in the server instance specification by using the form dbhost,SQL_port_number\SQLinstance. The Microsoft SQL default port number is 1433.


Click Next.


Confirm that all of the services to upgrade appear on the Ready to Upgrade page, and click Upgrade.

The Upgrading page and a progress indicator appear. When the upgrade process finishes, the Next button is enabled.


Click Next.


Click Finish.


Verify that all vCloud Automation Center services restarted.

All of the selected components are upgraded to vCloud Automation Center 6.1.
