CSC Unit Acquisition Fails -- Configuration looks good. What are suggestions to fix?

I am trying to add existing SonicWall TZ-300 with firmware, SonicOS Enhanced, to NSM 1.7. The acquisition hangs on Unit Acquisition. What should I look at to diagnose the error?


  • Enable Management using GMS
  • GMS syslog server port 514
  • Send Syslog Message to a Distributed GMS Reporting Server,, port 514
  • I see the Address Object of 'GMS Address' is created
  • The Firewall rules are updated to allow management to 443
  • SYSLOG is updated to include sending to


  • Device is defined by name and Serial Number
  • IP address is public IP of the SonicWall
  • Username and Password are Defined
  • Licenses are checked and good
  • Packet Monitor does NOT show any traffic to or from

What Next?

What do you suggest to fix or troubleshoot the connection?

Thank you

    Thank you, Larry

    Both of your comments have been dead on.

    The licensing is for NSM on my devices. When I started NSM, the popup indicated that migration was in the future, so I continued down the path to NSM 1.7. As it turns out, this advice is misleading.

    If I was managing hundreds of devices, I would have SonicWall updated the devices to use NSM, in the background. However, I support 16 SonicWalls. You can upgrade them yourself. Use

    • Edit the Cloud setting to On-Box. The CSC MA reference disappears
    • Move the device to the new tenant
    • Proceed with NSM 2.0
    • Also, on each device, you will have to enable Cloud management

    The SonicWall automatically creates the rules for management. There is a note in the knowledge base that CSC used only one address, A range may be used by NSM, - (Check the KBs)

    I have done this for a few of the devices. So no guarantee, yet.

    Thanks !

    @GMP Sorry I didn't include the full SOP for the manual migration earlier.

    But - for anyone else that is interested in spending an hour, rather than waiting for SonicWall - here you go.
