In the current release, CSM can only be upgraded using NSX CLI.


  • See Upgrading NSX Cloud Components to find the correct order to follow for upgrading CSM.
  • You must have extracted the file VMware-NSX-unified-appliance-<version>.nub from the NSX Cloud master upgrade bundle (MUB) and hosted on an FTP server accessible from CSM.


  1. Log in to NSX CLI with CSM admin credentials:
    $ssh <csm-admin>@<NSX-CSM-IP>
    and run the following NSX CLI command:
    nsxcsm> copy url scp://<username>@<ftp-server-ip>/<path-to-file>/VMware-NSX-unified-appliance-<version>.nub
  2. Extract and verify the file VMware-NSX-unified-appliance-<version>.nub:
    nsxcsm> verify upgrade-bundle VMware-NSX-unified-appliance-<version>
    Example output:
    Checking upgrade bundle /var/vmware/nsx/file-store/VMware-NSX-unified-appliance-<version>.nub contents
    Verifying bundle VMware-NSX-unified-appliance-<version>.bundle with signature VMware-NSX-unified-appliance-<version>.bundle.sig
    Moving bundle to /image/VMware-NSX-unified-appliance-<version>.bundle

        "history": []
      "state": 1,
      "state_text": "CMD_SUCCESS"
  3. Start the upgrade:
    nsxcsm> start upgrade-bundle VMware-NSX-unified-appliance-<version> playbook VMware-NSX-cloud-service-manager-<version>-playbook
    Example output:
    Validating playbook /var/vmware/nsx/file-store/VMware-NSX-cloud-service-manager-<version>-playbook.yml
    Running "shutdown_csm_svc" (step 1 of 6)
    Running "install_os" (step 2 of 6)
    Running "migrate_csm_config" (step 3 of 6)
    System will now reboot (step 4 of 6)
    After the system reboots, use "resume" to start the next step, "start_csm_svc".
      "info": "",
      "body": null,
      "state": 1,
      "state_text": "CMD_SUCCESS"
    Broadcast message from root@Autoimport-nsx-cloud-service-manager-thin (Fri 2017-08-25 21:11:36 UTC):
    The system is going down for reboot at Fri 2017-08-25 21:12:36 UTC!
  4. Wait for the upgrade to complete. CSM reboots during upgrade, and the upgrade is finalized when the CSM UI restarts after rebooting.
  5. Verify the version of CSM to confirm that it has upgraded:
    nsxcsm> get version


The CSM appliance is upgraded and the PCGs are automatically resized to 191 GB.

What to do next

  • If you are upgrading from version 2.4.x to 2.5.0 or later, or from 3.0.x to later, follow the steps here for Post-Upgrade Tasks because you have already upgraded NSX-T Data Center.
  • If you are upgrading from version 2.5.0 to later, proceed to Upgrading NSX-T Data Center.
