We had a cassandra cluster(DSE 2.1.1-1) with few nodes. We want to restore the data into new cassandra cluster(DSE 2.2.1).
The steps we followed below,
1. Took a snapshot from one of the node in existing cluster.
2. Brought up a new cluster with DSE 2.2.1
3. Just created a keyspace in the new cluster.
4. copied all the files from <snapshot>/<timestamp> to /var/lib/cassandra/data/<keyspace>/
5. started the cassandra service by using (dse cassandra)
But cant retrieve the data through cassandra-cli
We tried another option also.
1. Created keyspace and column families in the new cassandra cluster
2. restored the snapshot
This also not working.
Is there anything we missed?
Thanks in advance.
