You can upgrade VMware NSX (formerly NSX-T Data Center) from to 4.1.1 using the upgrade coordinator. The upgrade coordinator resides in the NSX Manager and orchestrates the upgrade process of ESXi hosts, NSX Edge cluster, and NSX management plane. The upgrade process involves upgrading the components in the following sequence: VMware NSX Edges, ESXi Hosts, and NSX management plane. If you are already using NSX 4.1.1 in the Telco Cloud Platform 5G Edition 3.0 environment, the NSX upgrade is not required for Telco Cloud Platform 5G Edition 3.1.


  1. Perform the Pre-Upgrade Tasks.

  2. Review the NSX Upgrade Checklist to track your work on the NSX upgrade process.

  3. Prepare your infrastructure for the NSX upgrade.

  4. Back up the NSX Manager of version


  • Upgrade NSX to 4.1.1.
    1. Upgrade the Upgrade Coordinator component.
    2. Upgrade NSX edges.
    3. Upgrade ESXi hosts.

      In case of SR-IOV enabled worker nodes or if the worker nodes cannot be migrated to another ESXi host, manually power OFF the worker node VMs to move the host into the maintenance mode.

      • Drain the pods from the worker nodes:

        kubectl drain <worker_node_name> --ignore-daemonsets --delete-local-data --force

      • Power OFF the worker nodes.

    4. Upgrade NSX manager.

What to do next

  1. Perform the post-upgrade tasks to verify that the NSX upgrade is successful.

  2. After the NSX upgrade is successful, verify that the clusters prepared for NSX are in the Success state:

    1. Log in to NSX Manager using Virtual IP (VIP) address.

    2. Navigate to System > Fabric > Node > Host Transport Nodes.

    3. Verify that all the clusters prepared for NSX are in Success state without any error.

    4. If there is an error on the ESXi hosts in the cluster, reconfigure the transport node by selecting the CONFIGURE NSX option on the cluster using the existing transport node profile. If there is any other upgrade issue, see Troubleshooting Upgrade Failures.
