I would like to migrate all the data in the table in a particular keyspace to a different syllaDB server. When I use the nodepool snapshot command, not all data is migrated, only certain parts of data are migrated. Each server is using the same version of syllaDB. Is there a best way to migrate these data?

> You could also use [Scylla Migrator](https://github.com/scylladb/scylla-migrator), which would read using CQL from one Scylla to another. It operates one table at a time.

So the migration when the source of the backup is restored to a different target cluster, that’s the data movement.
