Enhanced Linked Mode
Topology Changes
from vCenter Server 5.5
The implementation of Linked Mode has changed starting with vSphere 6.0.
You no longer need to join vCenter Server instances to Linked Mode
groups. You can access the replication functionality provided by Linked
Mode in vSphere 5.5 by registering multiple vCenter Server instances to
the same Platform Services Controller or joining
Platform Services Controller instances in the same vCenter Single Sign-On
domain.
To enable high availability between the vCenter Server instances in a single
vCenter Single Sign-On domain, the vCenter Server instances must use
the same site name.
Unlike the original Linked Mode, Enhanced Linked Mode is available and
supported on vCenter Server on Windows and vCenter Server Appliance.

Upgrade and migration from vCenter Server 5.5 to 6.5 supports only IPv4. You can reconfigure the
target deployment to IPv6 after upgrading or migrating.

Upgrade and migration from a mixed mode IPv4 and IPv6 environment transfers configurations
depending on the source deployment configuration.
