So now we have to migrate all the users from the old structure to the new one. In order to do that we are moving the user nodes from path A to path B. So it is like oldUserNode is deleted and a newUserNode is being created.
So, we need to find a way to replicate that node's deletion. Obviously I can't set the cq:distribute property since the node is not there anymore, so I need to find a way to (reverse) replicate that action to the other instances.
