Is it possible to change the cluster network on a production ceph?

Hello people,
   I am trying to change the cluster network in a production ceph. I'm having problems, after changing the ceph.conf file and restarting a osd the cluster is always going to HEALTH_ERROR with blocked requests. Only by returning to the previous configuration and restarting the same osd make the cluster going to OK. So, my question is: is it possible to change the cluster network on a production ceph without stopping the service and destroying data? If so, how?

Anticipated thanks
  Paulo Sousa
