             Summary: cassandra upgrade
                 Key: CASSANDRA-12902
             Project: Cassandra
          Issue Type: Wish
          Components: Tools
            Reporter: JianwenSun

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.
