Disclosed herein are system, method, and computer program product embodiments for performing a database migration with reduced downtime. Embodiments provide for migrating a source database table at a source database system to a target database table at a target database system. The embodiments provide for configuring the source database system to log changes to the source database table to a log, wherein the log is configured to replay the changes to the target database table and creating a replacement view table at the target database system, wherein the replacement view table provides access to current data from the source database table and the target database table. This approach allows access to the current data as replication continues without the need to take down access to the database.
