If you encounter any problems during the upgrade process, see Chapter 9 Troubleshooting the vRealize
Automation Upgrade.
Note While upgrading the Management Agent on the IaaS virtual machines, a VMware public certificate
is temporarily installed in your Trusted Publishers certificate store. The Management Agent upgrade
process uses a PowerShell script that is signed with this certificate. When the upgrade is finished, this
certificate is removed from your certificate store.
Prerequisites

Verify that the IaaS service hosted in Microsoft Internet Information Services (IIS) is running by
performing the following steps:
a Enter the URL https://webhostname/Repository/Data/MetaModel.svc to verify that the
Web Repository is running. If successful, no errors are returned and you see a list of models in
XML format.
b Log in to the IaaS Website and check that the status recorded in the Repository.log file reports
OK. The file is located in the VCAC home folder at /Server/Model Manager
Web/Logs/Repository.log.
Note For a distributed IaaS Website, log in to the secondary website, without MMD, and stop
Microsoft IIS temporarily. To ensure that the load balancer traffic is only going through the primary
Web node, check the MetaModel.svc connectivity, and restart the Microsoft IIS.
n
Verify that all IaaS nodes are in a healthy state by performing the following steps:
a Go to the management console for your primary virtual appliance by using its fully qualified
domain name, https://va-hostname.domain.name:5480.
b Log in with the user name root and the password you entered when the appliance was
deployed.
