while you are still in 3.6 engine you need to upgrade that Default cluster to 3.6. This requires VMs power cycle to fully update everything. only then upgrade to 4.1 > I also want to avoid creating a new cluster with 3.6 version cause then I > will have to shutdown all VMs again. you don’t have to again if you keep 3.6 cluster in 4.1 setup.
