Upgrading a Vyatta AMI

This section details how to upgrade a Vyatta AMI.

To upgrade the Vyatta AMI:

  1. Save your current system configuration (/config) to a separate location on your network.
  2. Using the new Vyatta AMI, create a new Vyatta virtual machine in your AWS environment. Use the instructions given in Chapter 1: Installing the System, starting in Obtaining and launching Vyatta NOS AMI.
  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 you saved onto the new Vyatta virtual machine.
  6. Reboot the system by using the reboot command. The system restarts with the new configuration.
