I am remember seeing a Pulumi guide on EKS cluster migration from older to newer version. But I am not able to find it now. Can anyone link?

I found this <https://www.pulumi.com/registry/packages/kubernetes/how-to-guides/eks-migrate-nodegroups/>

but I dont think this was it.. it was something else :thinking_face:

okay this says how to migrate nodegroups

where as I want to know how to migrate the cluster itself from older to newer version

What version are you trying to migrate to? We're  preparing the V3 release right now (in beta currently) and have a migration guide for that: <https://github.com/pulumi/pulumi-eks/blob/release-3.x.x/docs/eks-v3-migration.md>

This will be published to the docs as well once V3 is released

&gt;  What version are you trying to migrate to?
right now I am on k8s version 1.30 on EKS. I am not upgrading to 1.31 right away, but I want to build a upgrade path and upgrade it later.

Ah, I thought you wanted to upgrade the provider, not the k8s version.
When updating the cluster version you usually first upgrade the cluster, then the node groups and addons. You can run older nodegroups with newer clusters, but that only supports 1 minor version skew IIRC

just changing the version in cluster spec would work? sweet! thank you

I can recommend the EKS best practices as a general guide for upgrading: <https://aws.github.io/aws-eks-best-practices/upgrades/>
It list a good set of pre-checks and upgrade procedures
