Migrate data from 0.7 pre-release to 0.7 Beta
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

no.
1. if you delete system folder you'll blow away token information too,
which is not safe on > 1 machine. just delete the schema CFs
2. yaml is ignored, you need to explicitly run import-from-yaml (see NEWS)

Thanks Jonathan,
Just to make sure I understand, are you suggesting -
1. Delete system folder
2. Add the keyspace&cf definitions to cassandra.yaml
3. Restart
That should do it?

probably you will have to blow away the system schema CF and re-import from yaml
