You can use the GUI installer to perform an interactive upgrade of a vCenter Server appliance 6.7 or 7.0 in a High Availability (HA) cluster that uses an embedded vCenter Single Sign-On or Platform Services Controller to vCenter Server appliance 8.0. You must run the GUI upgrade from a Windows, Linux, or Macintosh computer that is in the same network as the appliance that you want to upgrade.
You can deploy version 8.0 of the vCenter Server appliance on hosts that are running ESXi 6.7 or later and on vCenter Server instances 6.7 or later.
A vCenter HA cluster consists of three vCenter Server appliances that act as Active, Passive, and Witness nodes. The Active vCenter HA node is upgraded using a migration-based upgrade while preserving the existing configuration.
Prerequisites
Stage 1 - Deploy the OVA File of the New vCenter High Availability Cluster
In stage 1 of the upgrade process, you deploy the OVA file for the new vCenter Server appliance.
Prerequisites
Ensure that your environment meets the prerequisites for upgrading a vCenter HA cluster. See Prerequisites for Upgrading vCenter Server High Availability Environments.
Procedure
Results
The newly deployed vCenter Server appliance 8.0 is running on the target server but is not configured.
Stage 2 - Transfer Data and Set-Up the Newly Deployed vCenter High Availability Cluster
When the OVA deployment finishes, you are redirected to stage 2 of the upgrade process to transfer the data from the old appliance and start the services of the newly deployed vCenter Server appliance. When the deployment finishes, vCenter Server has high availability protection.
Prerequisites
Understand the data migration options available to you when upgrading or migrating to a vCenter Server appliance with an embedded PostgreSQL database. You can select to migrate historical and other types of data in the background after deploying and starting vCenter Server. See Transferring Data from an Existing vCenter Server Appliance.
Procedure
Results
The vCenter Server appliance is upgraded. The old vCenter Server appliance is powered off and the new appliance starts.
After the Active node is upgraded, Auto Deployment automatically creates new Passive and Witness nodes using a clone operation. For Manual Deployment, nodes are not created automatically. You must clone the Passive and Witness virtual machines, and set the cluster mode to Enabled.
When the deployment finishes, vCenter Server has high availability protection. You can click Edit to enter Maintenance Mode, Deactivate, or Remove vCenter HA. You can also Initiate vCenter HA failover.
What to do next
