Our go-forward milestone is 2.9.0 and we backport as required. Is this needed in 2.8?

[cpinjani]

The base issue has milestone v2.8-Next1.
@kkaempf Can you please confirm the target milestone for this ?

[kkaempf]

The backend (aka eks-operator) fix will be shipped with 2.8-Next1.

I don't know the priority backlog of UI and if the issue at hand needs to be accelerated. Maybe @davidstauffer knows ?

I've been working on fixing the UI side, correcting any invalid ui errors and making sure cluster information correctly populates the form (pr here #11294); however, I found that I was not able to add node groups to imported EKS clusters with only self managed nodes. FYIU @cpinjani I filed a related issue #12872

[cpinjani]

Validation passed on the reported issue, able to perform cluster level edits on cluster.
