You can use the GUI installer to perform an interactive deployment of a Platform Services Controller appliance as the first instance in a new vCenter Single Sign-On domain or as a replication partner in an existing vCenter Single Sign-On domain. You must run the GUI deployment from a Windows, Linux, or Mac machine that is in the network on which you want to deploy the appliance.
Important:
You must deploy the replicating Platform Services Controller instances in a sequence.
