Subject Re: Copy data from 0.7.4 to 0.8
Date Thu, 06 Oct 2011 23:44:37 GMT
Copy the schema ("show schema" from the cli), then copy the sstables
using the bulk loader (http://www.datastax.com/dev/blog/bulk-loading).

You might have to migrate the schema manually (copy the Schema and
Migration system column families) if show schema doesn't work against
a 0.7 Cassandra.
