Migrate data from 0.7 pre-release to 0.7 Beta

[Mike Peters]

 Hi,

Is there a way to migrate data from a 0.7 pre-release build (June 30, 
2010) to the latest 0.7 beta 1?

Replacing the binaries and starting-up Cassandra, throws the "are you 
upgrading a pre-release version" error and dies.


Thanks,
Mike
