In the discussion around #39377 there is still concern that any import should be performed with the cluster shutdown - whether it is overwriting an existing realm or adding a new one. The general concern is that caching of the master realm or of the old realm may need to be cleared.
Since the import may be a long running operation and being shutdown introduces an outage window, we should work towards providing an alternative or at least documenting what issues may be seen if the cluster is not shutdown.
Currently the operator does not shut the cluster down, but instead when it completes the import of a new realm, will restart the cluster. This creates a reduction in service, but not a full outage. It's not clear if this stategy is valid given that it does create a window of time for possibly inconsistent behavior.
