Background information
Benefits
A lot of data migration tools are available. However, most of these tools are used for O&M and you have no permission to manage processes. Compared with these data migration tools, the database migration feature of DMS provides the following benefits:
- Integrates the security management capabilities of DMS, such as permission and process management.
- Integrates the data migration feature of Data Transmission Service (DTS) to provide services with high performance and concurrency. For more information, see High performance.
- Allows you to encapsulate service solutions to migrate databases, perform checks, and delete the migrated source databases. Then, you can update tenant routing configurations and collaborate linked services to enable seamless migration throughout the whole SaaS chain for applications.
Limits
- Allows you to migrate all tables, but not specific tables, in a database.
- Allows you to migrate full data, but not incremental data.
- Allows you to migrate only tables.
