Migrate from 0.6.5 to 0.7.2

[Zhong Li]

Hi all,

We want migrate from version 0.6.5 to version 0.7.2. Is there step by  
step  guide or document  we can follow?

Also there is new branch cassandra-0.7.2 on svn, what is purpose to  
create the new branch instead of one branch cassandra-0.7? Will you  
maintain both branches?

Thanks,

Zhong Li
