Stu Hood commented on CASSANDRA-1345:
-------------------------------------
> A workaround can be using sstable2json and json2sstable based data porting
Rather than using sstable2json, we should probably suggest that people use the
'snapshot' command before performing an upgrade.
> Cassandra 0.6.3 fails to restart if Cassandra 0.7 trunk (rev 981071) is run
> on the same data system store
