Local cluster has wrong provider after cluster migration


I tried to migrate my Rancher 2.6.3 installation from a K3S cluster to a GKE cluster following the process described in the docs. Migrating the setup worked fine, but now my local cluster still shows k3s as the provider. Also Rancher tries to upgrade the GKE cluster nodes to the version previously installed on the K3S nodes, which of course fails.

How do I get Rancher to recognize the correct cluster provider for it’s local cluster?
