    Hi Shah Khan , Thanks for posting your query on Microsoft Q&A.

    Resizing AKS instances in-place isn't supported. To change the size of an existing node in an Azure Kubernetes Service (AKS) cluster, you would need to create a new node pool with the desired size and then drain and cordon the old node pool.

    Please follow this document for step by step guidance on the same : https://learn.microsoft.com/en-us/azure/aks/resize-node-pool?tabs=azure-cli

    If you have any questions at all, please let me know in the "comments" and I would be happy to investigate further. Since I am based in PST timezone, I might not be able to get back to you immediately but should be able to response within 12 hrs.

    If this helped, please 'Accept answer' so that it an help others in the community facing the same issue.
