AWS T3 Instance

Here’s how to quickly make a T3 instance from a T2 instance.

  1. Take a snapshot of the EBS volume.
  2. Run the following AWS CLI command providing the snapshot ID and customizing the name and description properties:
aws ec2 register-image \
    --architecture "x86_64" \
    --ena-support \
    --name "AMI Name" \
     --description "AMI Description" \
    --root-device-name "/dev/sda1" \
    --block-device-mappings "[{\"DeviceName\": \"/dev/sda1\",\"Ebs\": {\"SnapshotId\": \"snap-000111222333444\"}}]" \
    --virtualization-type "hvm"

Now you can launch a T3 instance from the newly created AMI.

Update:

You can stop the instance, enable ENA on it, change the type to a t3, and start the instance. This does require the instance OS to support ENA.

aws ec2 modify-instance-attribute --ena-support --instance-id i-xxxxxxxx
