CAST AI automatically detects the presence of Karpenter autoscaler in your cluster and lets you migrate from Karpenter to CAST AI autoscaling with one click. You can easily migrate your Karpenter setup by importing Node Pools (or Provisioners) and EC2 Node classes (or AWS Node templates) as CAST AI's equivalent configurations: Node Templates and Node Configurations.

Node templates and node configurations that were created from Karpenter objects are now turned on and ready for you to use.
