Upgrade Path from 2.5.8 to 2.6.9

Hi Everyone, I have an old cluster that I’d like to bring into the modern era.

The cluster is running on EKS (v1.19.16) and is running Rancher 2.5.8

I realize that I will need to upgrade Kubernetes as I go.

I think the best path is:

  • Upgrade Rancher to 2.5.15
  • Upgrade Rancher to 2.6.3
  • Upgrade Kubernetes to 1.20.0
  • Upgrade Rancher to 2.6.7
  • Upgrade Rancher to 2.6.9

Does anyone know the right way to determine which releases I should skip?



I’m waiting the reply from expert of upgrading Rancher server
