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