Obviously;-) Sorry for that. The main reason I was looking into these things was, that I'm searching for the best way to migrate a 2.3.16 backend with ~4TB spools and ~80k users to 2.4. Unlike my other backends this one profits pretty much from singleinstancestore (many massmailings) and I don't want to loose these savings if possible. Simply upgrading the backend is impossible. The index upgrades will kill this machine. Since replication is not a possible way from 2.3.16 to 2.4 I tried to figure out if a simple XFER takes care about that. But it doesn't as far as I can tell. Do you know of a possible way to do that? Even if it's not trivial in the first place.
