ENA is a custom network interface optimized to deliver high throughput and packet per second (PPS) performance, and consistently low latencies on EC2 instances. Please use the following procedure to perform an in-place upgrade of AWS PV drivers, or to upgrade from Citrix PV drivers to AWS PV. The goal of this task is to upgrade from “Redhat to Citrix PV” and then from Citrix PV to AWS PV Drivers” Please refer to these articles on Driver Management on AWS, Windows clients, and servers. “How to remove a Printer from Windows 10 via PowerShell, Windows registry and Print Management, how to configure Windows instance using EC2 Launch for Server 2016, how to launch an EC2 instance, and how to apply Windows Updates from WSUS to the server using AWS RunCommand.

– Ensure you have the latest EC2Config services running on the server

Upgrading from Citric PV driver to AWS PV drive

– Ensure you create an AMI of the instance first (For possible “rollback”)
– Ensure you have Microsoft .NET Framework 4.5 installed on the server. See the following link for more information.

Step 2:
1. Ensure you download the latest AWS PV drive from this link
2. Download the latest driver package to the instance.
3. Extract the contents of the folder and then run AWSPVDriverSetup.msi.

– Then follow the Instruction steps as it basically a next and select process (select “i am ready” and as well as “i agree” follow by the many next windows :).

FYI: After running the MSI, the instance automatically reboots and then upgrades the driver. The instance will not be available for up to 15 minutes. After the upgrade is complete and the instance passes both health checks in the Amazon EC2 console, connect to the instance using Remote Desktop and verify that the new driver was installed. In Device Manager, under Storage Controllers, locate AWS PV Storage Host Adapter. Verify that the driver version is the same as the latest version listed in the Driver Version History table.
