If you are talking about an upgrade AFAIK 0.8 can read 0.6 SSTables, you will need to migrate the schema as described in the 0.7 upgrade info here https://github.com/apache/cassandra/blob/cassandra-0.7.6-2/NEWS.txt#L134
If you want to do a bulk dump / load take a look at sstable2json. Hope that helps. ----------------- Aaron Morton Freelance Cassandra Developer @aaronmorton http://www.thelastpickle.com On 10 Jun 2011, at 03:13, JKnight JKnight wrote: > Dear all, > > Could you tell me the best way to import data from Cassandra 0.6 to 0.8? > Thank you very much. > > -- > Best regards, > JKnight
