After you upgrade NSX-T Data Center, you can verify whether the versions of the upgraded components have been updated.


Perform a successful upgrade. See Upgrading NSX-T Data Center.


  1. From your browser, log in with admin privileges to an NSX Manager at https://nsx-manager-ip-address.
  2. Select System > Upgrade.
    You can also verify the networking related configuration from NSX-T Data Center 2.3 in the System and Advanced Networking & Security tabs.
  3. Verify that the overall upgrade version, component version, and initial and target product version are accurate.
    The status of the upgrade appears as Successful.
  4. (Optional) Verify that the Dashboard, fabric hosts, NSX Edge cluster, transport nodes, and all logical entities status indicators are green, normal, deployed, and do not show any warnings.
  5. (Optional) Verify the status of several components.
    • Fabric nodes installation
    • Transport node Local Control Plane (LCP) and Management plane agent connectivity
    • Routers connectivity
    • NAT rules
    • DFW rules
    • DHCP lease
    • BGP details
    • Flows in the IPFIX collector
    • TOR connectivity to enable the network traffic
  6. If you have an existing Ubuntu KVM host as a transport node, back up the /etc/network/interfaces file.
  7. If you have VIDM enabled, access your the local account at https://nsx-manager-ip-address/login.jsp?local=true.
  8. If you did not use NSX Policy Manager 2.3 to create your DFW rules, move your rules to the upgraded NSX Manager.
    1. Navigate to the Security tab and recreate your rules.
      Your pre-upgrade configuration is available under

      Advanced Networking & Security > Security > Distributed Firewall

    2. Navigate to Advanced Networking & Security > Security > Distributed Firewall and delete your pre-upgrade rules.
    3. Delete the infra_EC_to_FL_Connectivity_Strategy constraint to reset connectivity strategy.

      The connectivity strategy is set to NONE after the upgrade. To reset connectivity strategy, use an API call to delete the infra_EC_to_FL_Connectivity_Strategy constraint.

      DELETE https://<policy-mgr>/policy/api/v1/infra/constraints/<constraint-id>
