Is that possible to change the old type cni running cluster to new dynamic enhanced sunet support i.e separate pod subnet for new nodepools by removing old nodepools entirely. ?
Morning @KarishmaTiwari-MSFT
Are there any updates on this topic? We have the same requirements. I tried yesterday to add a new node pool with "new" CNI but failed.
So it would be good at least to know when such a feature is available.
Thanks in advance

Hi @Ankur Jain ,
Update - 8/25
Question: Is it possible to remove all old cni nodepool and create new nodepool with new cni? Not asking about the co-existence of both nodepool types in the existing cluster.
Answer: In the future release plan (shared below), this is how it will work -
Customers will be able to create new node pool with new CNI in their old clusters, move workloads from node pool running old CNI to the one running new CNI and then delete the old node pool.

Question: Could you please help if it is possible to migrate all old cni nodepool including small nodepool to enhanced cni and that way we can move old cluster to new dynamic cni ?
Based on the additional details you provided on your question, I reached out to the Product team to get more information and clarity on your ask.
They confirmed that - Unfortunately, this is not possible today. But they are working to build a solution that will allow customers to create new node pools in their old clusters with the new CNI and support co-existence of the two versions of the CNI in the same cluster. This should help scenarios like yours. They are discussing to build this capability in the upcoming semester. So this is something definitely on their roadmap but not supported at this point.
Hope that helps. Let me know if you have any other specific questions that I can help you with.

Query: Is it possible to change the existing AKS cluster from normal Azure CNI to dynamic allocation of IPs and enhanced subnet support?
You can’t add dynamic allocation of IPs and enhanced subnet support on an existing AKS cluster, since all cluster/node pools need to be either normal CNI or enhanced CNI. You would need to create a new cluster with the dynamic allocation of IPs and enhanced subnet support and migrate your workloads.
You can find more details on Dynamic allocation of IP addresses and enhanced subnet support in the FAQs here.
Hope that clarifies. Let me know if you have any questions or concerns.
@KarishmaTiwari-MSFT - Hi I have already gone through that doc but that doc missing information thats why I have posted here. Could you please help if it is possible to migrate all old cni nodepool including small nodepool to enhanced cni and that way we can move old cluster to new dynamic cni ?
I know tht nodepool can be migrated one by one for exising cluster so do you see any thing which will block or not meeting the requirements for existing cluster ?
In another way I am proposing a way out to check inputs from community if it is entirely possible in that way
@KarishmaTiwari-MSFT - Still I want to get final clarification on your reply is that - But they are working to build a solution that will allow customers to create new node pools in their old clusters with the new CNI and support co-existence of the two versions of the CNI in the same cluster.
My ask is - is that possible to remove all old cni nodepool and create new nodepool with new cni . I am not asking coexisting of both nodepool type here in exisintg cluster ?
@Ankur Jain
Thanks for your patience.
I got the confirmation from PG on this.

I hope that clarifies. I am happy to answer if you have further questions. Let me know in the comment.
@KarishmaTiwari-MSFT thanks for reply and getting the answer from product team to give actual thoughts to move in correct direction . Really appreciate your efforts.
Good to know if you could share which month or relase will be having such changes plan if any by pg team .
@Ankur Jain Thanks. I am glad your query is answered.
Regarding the new feature release plan, currently they could only share that it is being planned for next semester (i.e. somewhere between Jan 2023 -July 2023 timeframe). They will have a better idea about an estimated release in a couple of months. As I get more information on this in the near future, I will update this thread.
