 Upgrading the Mendix for Private Cloud Operator in a namespace will modify global resources such as Mendix Custom Resource Definitions in the cluster.
 
 [Custom Resource Definitions](https://kubernetes.io/docs/tasks/extend-kubernetes/custom-resources/custom-resource-definitions/) allow Mendix applications to be managed with Kubernetes APIs and tools such as `kubectl` and `oc`.
 
 Once you have installed a particular version of the Mendix Operator into any namespace in the cluster, you should not install older versions of the Mendix Operator into the same cluster, even if they are in other namespaces. This is because all the CRDs are global resources and operators in all namespaces use the same one, which may not be compatible across versions.
 
-Starting from `mxpc-cli` version 2.21.0, the installation or upgrade process will check to see if the cluster has a newer CRD version than the CRDs bundled with `mxpc-cli`. If the cluster has newer CRDs, `mxpc-cli` will skip the CRD installation step - and avoid downgrading CRDs.
