Before upgrading your ProxySG virtual appliance (VA) on AWS, review the following information.
The following table outlines the pros and cons for the two upgrade methods.
If you are upgrading to a version of SGOS that changes the major version (for example, upgrading from 6.7.5.x to 7.3.x), use the Create/Destroy method.
All initial or new deployments should be created using the latest AMI from the AWS Marketplace listing. Using the latest AMI ensures that your VA is running on a supported instance type and has the correct networking enabled (SR-IOV). For upgrades after the initial deployment, you can download a build from the Broadcom Support portal.
Note: If you did not originally download the ProxySG VA from AWS Marketplace, you should use the Create/Destroy method to upgrade.
The Load/Upgrade method is the same method used to upgrade physical ProxySG appliances. This method is also applicable to ProxySG VAs running on AWS. After performing this method and confirming the upgrade was successful, delete the version of SGOS from the installed system images. Deleting the previous version will prevent any unintentional downgrade in case of boot failures.
To perform the Load/Upgrade method:
# (config) upgrade-path "http://xxx.xxx.xxx.xxx/path/to/file.bcsi"
# load upgrade
# restart upgrade
# (config installed-systems)delete 2

In this method, you create a new ProxySG instance and load your configuration and policy into it. To upgrade using this method:
