You cannot back down to a previous version of Server Management with PUT. You must use the cmicimageupdate utility from another EC2 instance managed by the CMIC. The steps below use Viewpoint as the example.
You cannot back down to a version earlier than the minimum version allowed on Teradata Software for AWS.
- Download the latest CMIC image to which you want to back down from the Teradata customer portal. New and existing Teradata customers with on-premises Teradata systems can use the Teradata customer portal to download the CMIC image.
- From the AWS Web Console, note the Private IP and Public IP of the CMIC instance.
-
From your SSH client console, log onto the Viewpoint instance as ec2-user using the applicable AWS key pair.
ssh -i private key file.pem ec2-user@Viewpoint private-IP
where:- The private key file.pem is the private key file of the AWS key pair specified when deploying the instance.
- The CMIC private-IP is private IP address of the CMIC instance.
-
Run the configuration utility.
./cmicimageupdate --cmic public-IP --identity private-key-file.pem --image CMIC image.cif
where:- The public-IP is the public IP address of the CMIC instance.
- The private-key-file.pem is the private key file of the AWS key pair specified when deploying the instance.
- The CMIC image.cif is the name of the downloaded CMIC file.
- When prompted, type yes to continue. The utility updates the CMIC version.
