<@U01ULUUEGG5> can you share the code you're attempting? you can definitely have multiple node groups

Hi <@UCWG26BH7>, thanks for getting back to me. In this case I didn't declare the node groups manually, instead using the `eks.Cluster` input property `nodeGroupOptions` to create the groups. In attempting to declare another `eks.NodeGroup` manually I am receiving the error message mentioned above. I am interpreting this to mean `nodeGroupOptions` are a convenient way to create single node groups but whenever you need any more complex configurations you should use `eks.NodeGroup` or `eks.ManagedNodeGroup`.

My problem now is I have live infrastructure setup using `nodeGroupOptions` but need to migrate, with zero downtime, over to the more flexible manual declarations. This was proving difficult due to the approaches being incompatible with each other. I had a realisation last night at I could just remove the nodegroups from the Pulumi state to keep them running but allow Pulumi to create new node groups alongside them.
