Abstract: Data is migrated between a source database and a target database. The source database management system (“DBMS”) remains operational during the migration. A user selects the source DBMS and target DBMS, provides connection information used to connect to the database management systems and selects a virtual machine instance to perform the migration in conjunction with a database migration service. After the setup is complete, the virtual machine instance in conjunction with the database migration service performs data type transformations, and other operations, without user intervention. The database migration service also converts, without user intervention, the source schema and code to a format compatible with the target DBMS. Any code that is not converted is marked to assist the user of the database migration service identify where manual re-coding is required. The database migration service can also provide recommendations as to a target DBMS that is a suitable target DBMS.

Abstract: A hosted database service may receive a request to replicate data between two locations. Data may be replicated serially during an initial observation period. During the observation period, replication data may be analyzed to detect access patterns involving transaction delimiters and sequential or closely-timed access to data. Related tables may be assigned to replication groups. Replication data for the replication groups may be sent and processed in parallel. During parallel replication, effectiveness of the replication data may be monitored and the replication groups may be periodically readjusted.
