I could take the whole system down if it would become necessary for a massive upgrade or alike.

Well, then there are two things I am missing: - to have all data replicated (still does not work for me, I am already thinking about moving the whole setup to another subnet to get rid of 0-s :) not really, I'd like to rather solve it in the right way - to be sure that the old servers (those you leave up-and-running) will be able to talk to the upgraded one? While the first problem is probably just an irritating bug, the second one should have forced you to do something else sometimes - not all coda releases were compatible with each other (protocol and packet format), I think?
