Run Command, State Manager, the CloudWatch agent, and domain join support have been moved into another agent called SSM Agent. SSM Agent will be installed as part of the EC2Config upgrade. For more information, see EC2Config and AWS Systems Manager.

If you have a proxy set up in EC2Config, you will need to update your proxy settings for SSM Agent before upgrading. If you do not update the proxy settings, you will not be able to use Run Command to manage your instances. To avoid this, see the following information before updating to the newer version: Installing and Configuring SSM Agent on Windows Instances in the AWS Systems Manager User Guide.

If you previously enabled CloudWatch integration on your instances by using a local configuration file (AWS.EC2.Windows.CloudWatch.json), you will need to configure the file to work with SSM Agent.
