Hi Adam,

I would love to be running 2.4.x. Unfortunately, because replication does
not work from old version 2.3.x to newer 2.4.x "some re-indexing pain"
is from everything I have read here a completely uncontrolled I/O storm
on your disk subsystem unless you have a prolonged service outage. I
really, really, really hope that 2.4.x will be able to replicate to
2.5.x. Then you can upgrade the relatively unloaded replica, fail-over
to the new version and then upgrade the replica for a virtually
seamless procedure. Now we are looking for idle usage periods together
with a folder tickle script to stagger the upgrade process I/O.
