Download the IaaS installer to the virtual machine where the IaaS components to be upgraded are installed.
Before you begin
Verify that Microsoft .NET Framework 4.5.2 or later is installed on the IaaS installation virtual machine. You can download the .NET installer from the VMware vRealize Automation IaaS Installation page. If you update .NET to 4.5.2 after you shut down the services, the virtual machine might restart as part of the installation. When this happens, you must manually stop all IaaS services on the virtual machine except for the Management Agent.
If you are using Internet Explorer for the download, verify that Enhanced Security Configuration is not enabled. Enter res://iesetup.dll/SoftAdmin.htm in the search bar and press Enter.
Log in as a local administrator to the Windows server where one or more of the IaaS components you want to upgrade are installed.
About this task
If you see certificate warnings during this procedure, you can ignore them.
Except for a passive backup instance of the Manager Service, the startup type for all services must be set to Automatic during the upgrade process. If you set services to Manual, the upgrade process fails.
- Open a Web browser.
- Enter the URL for the VMware vRealize Automation IaaS Installation page.
For example, https://vcac-va-hostname.domain.name:5480/installer, where vcac-va-hostname.domain.name is the name of the primary or master vRealize Automation appliance node.
- Click IaaS installer.
- The installer file, firstname.lastname@example.org, is sent to the Downloads folder by default.
Do not change the filename. It is used to connect the installation to the vRealize Automation appliance.
