Thanks Otis, but this is not my case. Most of my fields are not stored , but I do have the original data in case I need to reindex. My question is do I need to? If my 1.4.1 can be read by 3.1, I assume 3.1 can continue to write to it? In that case, I continue assuming that 4.0 will know how to read only the new segments, and if I optimize it, than I will have only one new segment, created by 3.1, thus readable by 4.0. It makes sense to me, the only question is if my guesses are right:-) Thanks.
