• Trying to uninstall NSX-T.
• All Transport nodes, segments and Edges have already been removed and no other NSX-T objects are present in vCenter.
• There is only one NSX-T manager left.
• When attempting to remove the vCenter server (Compute Manager) from NSX you get the following message:

• Removing the last NSX manager cannot be done via Delete Compute Managers in NSX-T manager UI.
