Restricted users created using `--restricted-auth-permission` flag need to pass mandatory flags: '`--rbd-data-pool-name`(if it is a rbd user), `--k8s-cluster-name` and `--run-as-user`' flags while upgrading, in case of cephfs users if you have passed `--cephfs-filesystem-name` flag while creating csi-users then while upgrading it will be mandatory too. In this example the user would be `client.csi-rbd-node-rookstorage-replicapool` (following the pattern `csi-user-clusterName-poolName`)

!!! note
An existing non-restricted user cannot be converted to a restricted user by upgrading.
The upgrade flag should only be used to append new permissions to users. It shouldn't be used for changing a csi user already applied permissions. For example, you shouldn't change the pool(s) a user has access to.
