6.7

System Requirements for the New
vCenter Server Appliance and
Platform Services Controller Appliance
The upgrade of the appliance is a migration of the old version to the new version, which includes
deploying a new appliance of version 6.7. You can deploy the new vCenter Server Appliance or
Platform Services Controller appliance on an ESXi host 6.0 or later, or on a vCenter Server instance 6.0
or later. Your system must also meet specific software and hardware requirements.
When you use Fully Qualified Domain Names, verify that the client machine from which you are deploying
the appliance and the network on which you are deploying the appliance use the same DNS server.
Before you deploy the new appliance, synchronize the clocks of the target server and all vCenter Server
and Platform Services Controller instances on the vSphere network. Unsynchronized clocks might result
in authentication problems and can cause the installation to fail or prevent the appliance services from
starting. See Synchronizing Clocks on the vSphere Network.
Hardware Requirements for the vCenter Server Appliance and
Platform Services Controller Appliance
When you deploy the vCenter Server Appliance, you can select to deploy an appliance that is suitable for
the size of your vSphere environment. The option that you select determines the number of CPUs and the
amount of memory for the appliance. The size of the Platform Services Controller appliance is the same
for all environment sizes.
Hardware Requirements for the vCenter Server Appliance
The hardware requirements for a vCenter Server Appliance depend on the size of your vSphere
inventory.
