Before you upgrade a vCenter Server and ESXi hosts registered to vCloud Director, you must upgrade each NSX Manager associated with that vCenter Server.
Upgrading NSX Manager interrupts access to NSX administrative functions but does not interrupt network services. You can upgrade NSX Manager before or after you upgrade vCloud Director, whether or not any vCloud Director cells are running.
For information about upgrading NSX, see the NSX for vSphere documentation at https://docs.vmware.com.
- Upgrade the NSX Manager associated with each vCenter Server registered to your vCloud Director installation.
- After you have upgraded all your NSX Managers, you can upgrade your registered vCenter Server systems and ESXi hosts.
