@Girish Prajwal Since ACI is just running instances of containers there's no reason you couldn't move those containers to AKS. The issue is more that there's no quick and easy guide or 'push button option' because AKS is far more complex/capable than ACI. It's like having a 'car to fighter jet' migration tool or process. It's possible, but a quick and/or automated approach will likely end in failure.
If you are already running in AKS, you should be able to pretty easily take their ACI deployment config (image, ports, volumes, etc) and build out a Kubernetes manifest for the deployment and service. If you aren't already using Kubernetes/AKS, then you will have to establish their clusters and managing Kubernetes in production.
Hope this helps!
