We are moving a dev cluster into production and we want to remove NSX from it. I´m following the guide to "Safely Remove an NSX Installation" from a cluster but cant disconnect the cluster (cluster is grayed out). I deleted all logical switches and edges in preparation, and the NSX controller and manager are connected to a different port group.
NSX version 6.4.5 Build 13282012
ESXi, 6.7.0, 13006603
