<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:EN-US">our experiences are add and delete new/old nodes is working only if this node is no quorum node in an ccr cluster, no problem. There are no mmshutdown steps necessary. We are on 4.2.3.6.
I think this is already available since >4.2. If you want to add a new quorum node, than you must put this node first as a client and after that you can change this node to a quorum node.<o:p></o:p></span></p>
