Amazon EKS v1.26

In-Place Upgrades to Amazon EKS v1.26 using Rafay

In our recent release in July, we added support for in-place upgrades of existing EKS clusters to Kubernetes v1.26. Customers tell us that they wish to be extremely careful with in-place upgrades of their existing EKS clusters because there is no benefit in rushing this and impacting mission critical applications etc. Provisioning of new EKS v1.26 clusters using Rafay has been supported for a while now.

Upgrade to EKS v1.26


Organizations that wish to perform sophisticated checks for API deprecation etc are strongly recommended to use Rafay's Fleet Operations for Amazon EKS.

Amazon EKS v1.26 Clusters using Rafay

In our recent release in May, we added support for a number of new features and enhancements. One of these was support for new EKS cluster provisioning based on Kubernetes v1.26.

Customers have shared with us that they would like to provision new EKS clusters using new Kubernetes versions so that they do not have to plan/schedule for Kubernetes upgrades for these clusters right away. On the other hand, they want to be extremely careful with their existing clusters and plan/test in-place upgrades for these. There is no benefit in rushing this and impacting mission critical applications etc.

Based on this feedback, starting this release, we plan to introduce support for new Kubernetes versions for CSPs (i.e. EKS, AKS and GKE) in two phases. In the first phase, which will come very quickly, we will support new cluster provisioning for the new Kubernetes version. This requires us to extensively validate support for ALL supported interfaces in the platform (See details below). We will follow up with a Phase 2 which will bring support for zero touch in-place upgrades.


Support for zero touch, in-place upgrades in Rafay from EKS v1.25 to v1.26 will follow in a few weeks. This requires us to add support for new preflight tests etc and perform extensive testing and validation.
