> Hey guys, is it possible to upgrade cassandra from 1.2.4 to 3.x directly
> without rolling upgrade from version to version. We have huge database of
> data in produce env and it will cost lot of time for us to upgrade sstable
> step by step. We just want to set up the 3.x cluster and restore the upgraded
> data(by one time if possible).
> Any good idea? Thanks.
