VMware NSX version 6.2 and later supports combining multiple vCenter Server / VMware NSX domains under one management domain. While vCenter Server – NSX Manager coupling still exists, one NSX Manager is acting as primary. Only one universal NSX Controller cluster is deployed by the primary NSX Manager. Secondary NSX Manager instances do not deploy the NSX Controller cluster.

The management cluster NSX Manager acts as primary, and all resource group NSX Manager instances are secondary.
