To expand on that FAQ, the detailed process should be to - configure the new servers
- update the configuration on the old servers - restart each old server one at a time - start the new servers - have your applications reconnect with the full set of servers in the connection string. This can be done whenever you like. Your clients will receive a disconnect message when the server that they are talking to is restarted, but they should reconnect immediately and transparently. You may have a problem if your applications don't handle transient disconnections properly.
