So I have been doing a evo server kind of like how a few yt's have been doing just with slightly different rules. I have a server and everytime I try to upgrade it by removing the jar from the old version and changing it to the new one, in the console it tells me it has converted and when I log on its the same world but as we had never touched a single block in it. We are changing from version beta 1.2_02 to beta 1.4_01. Anyone know how we can upgrade without loosing progress?
