Hi Roland. The short answer is - I'm not sure because I'm in the midst of doing this myself, but my setup is just Replicated.
I believe that you can do what you said with the clients because they are the only entities with knowledge of what servers are in the backend, so adding new servers to their configs and restarting those clients should work just fine, assuming you get the replication/distributed part of their configs correct. The one thing is, from what I understand, no rebalancing of old files will take place on the new servers automatically - that's a manual procedure - but any new files written by the clients will be hashed out to all servers - including the new ones. Just for my information - did you add the extra servers for capacity / redundancy / performance increases?
