AWS Database Migration Service now supports enhanced premigration assessments

Starting today, you can use enhanced premigration assessments to identify potential database migration problems before initiating your migration. Once the migration task is set up, a premigration assessment scans both the source and target database schemas and the migration task settings to identify a list of potential issues ranging from a data type mismatch to possible performance issues. You can select one or more premigration assessments to run on your database migration tasks and review the results on the console or in an AWS S3 bucket.
