Amazon Database Migration Service (DMS) has expanded the functionality of premigration assessments. A premigration assessment evaluates the source and target databases of a database migration task to help identify any problems that might prevent a migration from running as expected. By identifying and fixing issues before a migration starts, you can avoid delays in completing the database migration. This feature is now available in Amazon Web Services China (Beijing) Region, operated by Sinnet and Amazon Web Services China (Ningxia) Region, operated by NWCD.

With this enhancement, the premigration assessments can obtain more detailed information about the source schema and tables to provide recommendations on the Amazon DMS settings that should be used. For example, the assessment can suggest which method of reading redo logs for CDC should be used or check if the recommended settings have been enabled, providing best practice recommendations from Amazon DMS experts.
