The process completed very smoothly and created a performance boost for almost every workload we had. I think keeping ext3 around is really convenient to compare against ext4 as it becomes more mature, but outside of its academic use I don't see any good reason to keep it around. With such an easy migration path for users (mount as ext4 in place) I think an "end of life" plan should not be that complicated and encouraged. mrubin
