DSE migration toolkit
The DataStax Enterprise (DSE) migration toolkit includes the DataStax migration tools that you can use to migrate your data across DSE and another Apache Cassandra®-based database, such as Astra DB or HCD.
This documentation doesn’t describe all possible migration paths; it focuses on migrations using DataStax migration tools like ZDM Proxy.
Migrate your data
The tools and process for data migration to or from DSE depends on your DSE version and the other database’s platform or version.

Migrate data from DSE
The following information provides guidance on migrations to DSE.
Generally, DataStax recommends migrating to the latest version of DSE, unless you have a compatibility issue that requires an interim migration to an earlier version before upgrading.
When migrating from DSE to another Cassandra-based database, follow the migration guidance for your target database to determine cluster compatibility, migration options, and recommendations. For example, for Astra DB, see Astra migration toolkit, and for HCD, see HCD migration toolkit.
If your target database isn’t directly compatible with a migration from DSE, you might need to take interim steps to prepare your data for migration, such as upgrading your DSE version or modifying the data in your existing database to be compatible with the target database.
Migrate your code
After migrating your data, your applications can connect exclusively to your new databases.
If you are already using a compatible Cassandra driver, you can modify the driver connection string to connect to the new databases. For some migrations, changing the connection string might be the only change you need to make to your code. However, you might want to update your code to take advantage of features and improvements available in your new database platform or a newer driver version.
For database-specific connection information, see the documentation for your target database and version.
