Upgrading the full VHD

How to upgrade the full VHD when Hyper-V specific content is changed.

When Hyper-V-specific content in the vRouter VHD is changed, you must perform an upgrade to the new VHD, using the procedure in this section.

To upgrade the vRouter VHD:

  1. Save your current system configuration (/config) to a separate location on your network.
  2. Using the new vRouter VHD, create a new virtual machine in your Hyper-V environment. Refer to the instructions in Installing the Vyatta NOS Hyper-V VHD.
  3. Perform initial configuration of the new virtual machine and test the installation to verify connectivity on the network.
  4. Shut down the old system so that it does not conflict with the new system.
  5. Load the configuration that you saved onto the new vRouter virtual machine.
  6. For each Ethernet interface in the loaded configuration, delete the hardware ID.
    In configuration mode, use ​delete interface ethernet ethx hw-id​, where ​​​ethx​​​is the name of the Ethernet interface.
  7. Reboot the system by using reboot.
The system restarts with the new configuration.
