A migration is a workflow that encompasses the lifecycle of uploading and importing your data to the selected databases. DataStax can migrate all data, however critical, with acceptable or zero downtime. When the migration is complete, the data is present in the new database and all client applications connect exclusively to the new database. The old database becomes obsolete and can be removed.

Astra DB is designed to handle high-performance requirements, making it suitable for applications that need low latency and high throughput. The tool, Zero Downtime Migrator (ZDM), moves your data to Astra DB with no downtime and with minimal configuration changes.

For detailed instructions and additional resources, refer to the DataStax documentation on data migration. This documentation provides comprehensive guidance on using the migration tools, including scenarios for zero-downtime migration.
