I've got a new server coming in and I have no interest in putting 4.10 on it. I'm comfortable with 5.2.1 - but i'm wondering what the upgrade from 5.2.1 to 5.3 will be like once 5.3 hits stable. I'm considering running 5.3 beta for a month, but I would prefer 5.2.1 if the upgrade will be trivial. Thanks, dan
