Migrating from an embedded VMware vCenter Single Sign-On deployment to an external depends on the current topology of your environment. Use the examples below to determine your current VMware vCenter Single Sign-On deployment and the steps required to migrate to an external VMware vCenter Single Sign-On topology prior to upgrading to VMware vSphere 6.0.
A single VMware vCenter Single Sign-On embedded VMware vCenter Server
In this example, you have VMware vCenter Server with VMware vCenter Single Sign-On installed on the same machine with no additional VMware vCenter Servers in the vCenter Single Sign-On domain.
A VMware vCenter Single Sign-On embedded VMware vCenter Server with a VMware vCenter Server node in the same VMware vCenter Single Sign-On domain
In this example, you have VMware vCenter Server with VMware vCenter Single Sign-On installed on the same machine with an additional VMware vCenter Server pointing to the embedded instance of VMware vCenter Single Sign-On.
A VMware vCenter Single Sign-On embedded VMware vCenter Server with an additional VMware vCenter Single Sign-On embedded VMware vCenter Server in the same VMware vCenter Single Sign-On domain
In this example, you have VMware vCenter Server with VMware vCenter Single Sign-On installed on the same machine with an additional VMware vCenter Server with VMware vCenter Single Sign-On installed on another machine. Both deployments are a part of the same VMware vCenter Single Sign-On domain.
One VMware vCenter Single Sign-On embedded VMware vCenter Server node with an additional external VMware vCenter Single Sign-On node in the same VMware vCenter Single Sign-On domain
In this example, you have VMware vCenter Server with VMware vCenter Single Sign-On installed on same machine with an additional external VMware vCenter Single Sign-On node. Both deployments are a part of the same VMware vCenter Single Sign-On domain.
