MIgrating from self-managed Cassandra to Keyspaces

Question

Running a Cassandra cluster on Kubernetes and is considering a move to Keyspaces.

It is unclear on how to export the data from the existing cluster and import it into Keyspaces?

Would they just use cqlsh COPY?

Yes,  use `cqlsh`:

At the moment, doesn't look like Keyspaces is a supported target for DMS.

Rafael Mosca · Answer

Yes, but is not the only option.
- for small datasets or tables you can [load data into Amazon Keyspaces using `cqlsh`](https://docs.aws.amazon.com/keyspaces/latest/devguide/bulk-upload.html). 
- for production workloads with large datasets, you can [use the DataStax Bulk Loader for Apache Cassandra to load data into Amazon Keyspaces](https://docs.aws.amazon.com/keyspaces/latest/devguide/dsbulk-upload.html) using the `dsbulk` command.
