To enable Enhanced Linked Mode, all you need to do is make the PSCs corresponding to the vCenter Servers participate in the same SSO domain. For instructions on how to perform this activity, refer to the Deploying External Platform Services controllers section of this chapter. Keep in mind, though, that you will only be able to join/pair PSCs during its installation or deployment.

In scenarios where you intend to link already deployed vCenter Servers, deploy a new PSC in the same SSO domain and repoint one of the vCenter Servers to the newly deployed PSC. For instructions on how to repoint vCenter to PSC, read the VMware Knowledge Base article How to repoint vCenter Server 6.x between External PSC within a site (2113917) https://kb.vmware.com/kb/2113917.
