What happens if two GitLab servers both use the same k8s cluster for Auto DevOps

I’m migrating some projects from a CE server to an EE server. The old one is managing a k8s cluster we deployed to AWS. I’d prefer to transfer the k8s cluster over instead of recreating it. Has anyone ever done this? In particular, I’d like to know:

  1. Can I have two different gitlab servers pointing to the same k8s cluster?
  2. Can I disable one, enable the other, then continue DevOps without interruption?
