Architecting a vCloud Director Solution : Operational Considerations : 11.2 VMware vCloud Director Patching : 11.2.2 NSX Manager and NSX Edge Instances
   
11.2.2 NSX Manager and NSX Edge Instances
NSX Manager is patched manually by uploading a patch file to the appliance.
Existing NSX Edge instances can be updated manually by resetting the NSX Edge vApp network or redeploying the edge gateway in the vCloud Director UI. Upgrading NSX Edge version 5 to version 6 through NSX Manager is currently not supported (as of vCloud Director 8.0).
Upgrade of NSX Controller instances and ESXi host vib components is done from within NSX management interface.
